Plaintiff-Appellee,
v
No. 221263
Oakland Circuit Court
LC No. 86-075225-FC
JON W. GUMBLE,
Defendant-Appellant.
Before: Doctoroff, P.J., and Murphy and Zahra, JJ.
PER CURIAM.
The history of this case is expansive and the procedural aspects are somewhat complex.
Defendant was charged with open murder, MCL 750.316, and possession of a firearm during the
commission of a felony, MCL 750.227b, for the May 24, 1986, murder of Lee Garretson, Jr.
Defendant’s first jury trial took place in 1987, and he was convicted of second-degree murder,
MCL 750.317, and felony-firearm. Defendant was sentenced to forty-eight to eighty years for the
murder conviction, and to a two-year consecutive term for the felony-firearm conviction.
Defendant appealed as of right and this Court reversed defendant’s convictions and remanded for
a new trial. People v Gumble, unpublished opinion per curiam of the Court of Appeals, issued
September 12, 1989 (Docket No. 112617).
Defendant’s second jury trial was held in February 1990. During trial, defense counsel
repeatedly failed to adhere to rulings made by the trial court and a mistrial was declared.
Defendant’s third jury trial was held in May 1990. Defendant was convicted of voluntary
manslaughter, MCL 750.321, and felony-firearm. Defendant was sentenced to six to fifteen
years for the manslaughter conviction and a two-year consecutive term for the felony-firearm
conviction.
While his appeal of right was pending, defendant filed a motion to remand with this
Court seeking a remand for the purpose of filing a motion for a new trial based on newly
discovered evidence. After appealing this Court’s denial of his motion, our Supreme Court
ordered the matter decided on the merits or remanded to the trial court for the motion for new
trial. The matter was remanded to the trial court. Pursuant to a subsequent order by the Supreme
Court, this Court decided the merits of defendant’s appeal as of right and affirmed defendant’s
convictions and sentences. People v Gumble, unpublished opinion per curiam of the Court of
Appeals, issued August 25, 1995 (Docket No. 131623). Defendant’s motion for a new trial
-1-
based on newly discovered evidence was later heard and denied by the trial court. Defendant
appealed the denial of his motion and this Court remanded for an expanded evidentiary hearing
and further factfinding. People v Gumble (After Remand), unpublished opinion per curiam of the
Court of Appeals, issued May 2, 1997 (Docket No. 191372).
On remand, the trial court held a two-day evidentiary hearing and denied defendant’s
motion for a new trial. Defendant filed a claim of appeal with this Court on August 3, 1999. In
an order dated September 30, 1999, this Court dismissed the claim of appeal for lack of
jurisdiction, finding the April 14, 1999, order denying the motion for new trial a postjudgment
order not appealable as a matter of right. Defendant filed a motion for rehearing and this Court,
on its own motion, vacated its September 30, 1999, order dismissing the case, treated the claim
of appeal as if it were an application for delayed appeal, and granted the application. This Court
limited defendant’s issues on appeal to those raised on remand. We reverse.
In order to prevail on a motion for a new trial based upon newly discovered evidence, a
defendant must demonstrate that (1) the evidence itself, not merely its materiality, is newly
discovered, (2) the evidence is not merely cumulative, (3) the evidence is such as to render a
different result probable on retrial, and (4) the defendant could not with reasonable diligence
have produced it at trial. People v Lester, 232 Mich App 262, 271; 591 NW2d 267 (1998). We
review a trial court's decision on such a motion for an abuse of discretion. Id.
Defendant contends that Jerry Mayberry’s confession and the Kelly Ridenour-Archdale
police report meet the requirements of the above formulated standard. In People v Gumble (After
Remand), unpublished opinion per curiam of the Court of Appeals, issued May 2, 1997 (Docket
No. 191372), this Court held:
A review of the hearing and court’s findings leads us to conclude the court
acted prematurely in denying the motion. We disagree with the prosecutor’s
contention the evidence was not newly discovered or was discoverable and
producible at trial with reasonable diligence. People v Davis, 199 Mich App 502;
503 NW2d 457 (1993). It is true defendant consistently maintained Mayberry and
another individual, Billy Beaumont were involved in an armed robbery of his
home on the night of the murder. Nonetheless, contrary to the prosecutor’s
assertions, it would not have benefited defendant’s case to call either man at trial
because both denied involvement at that time. It is not the fact defendant alleges
these men were involved in the murder that is newly discovered. Instead it is the
later confession suggesting their involvement that constitutes new evidence. Nor
do we believe the evidence was merely cumulative. The evidence constituted
direct support of defendant’s theory of defense and was not presented by other
means during trial. People v Machura, 25 [sic] Mich App 481; 517 NW2d 797
(1994).
The more difficult question is whether introduction of Mayberry’s
confession would probably have caused a different result. Although we are
generally skeptical of confessions made by prison inmates who seemingly have
nothing to lose by confessing to a crime committed by another, we note in this
case Mayberry was informed before giving the confession that implicating himself
-2-
in the robbery could result in his prosecution for felony-murder and a resulting
prison sentence of life without the possibility of parole.
Nonetheless, were this the only “new evidence” proffered by defendant we
would not be able to say the court abused its discretion in denying the motion.
However, defendant also offers the discovery of a statement made by Kelly
Ridenour, Beaumont’s former girlfriend, to the police. In this statement Ridenour
informed the police Beaumont told her he and Mayberry robbed defendant’s home
using masks and a gun and that she was shown the masks. The trial court appears
to have determined Ridenour’s statement was not corroborative of defendant’s
theory because Beaumont allegedly told her he shot the victim and this version
conflicts with defendant’s position he shot the victim believing him to be one of
the robbers. We do not believe this conflict in the stories renders Ridenour’s
statement unconvincing or incredible. It is not uncommon for offenders to brag
and exaggerate about offenses committed. In fact it is often an offender’s
description of his crime to another that helps lead the police to the offender. We
cannot say Mayberry’s confession supported by Ridenour’s statement may not
have lead to a different outcome at trial without a better record of Ridenour’s
proposed testimony. This is especially true in light of the fact the jury convicted
defendant of the lessor crime of manslaughter rather than the charged crime of
second[-]degree murder. However, because it was never determined below
whether defendant was in possession of Ridenour’s statement prior to trial or the
exact nature of the proposed testimony by Ridenour, we remand for a full
evidentiary hearing on the newly discovered evidence in which Ridenour is to be
called to testify.
Defendant contends that Ridenour’s testimony constituted direct support for defendant’s
theory of the case. Her testimony confirmed that William Beaumont intended to rob defendant or
the victim, that Beaumont and Mayberry wore masks and carried a long gun and that defendant
fired a shot while in the bedroom. The trial court, however, held that it found the prosecutor’s
testimony persuasive that she disclosed the Ridenour report to defendant. The court further
stated:
Although there are unanswered questions such as why Ms. Ridenour was not
called at trial, why the prosecutor never followed up on potential charges against
Mr. Beaumont, why Officer Bailey[1] never mentioned his discussions with Ms.
Ridenour at trial. The Court does find that the police report regarding Ms.
Ridenour and the information she had was not withheld from the Defendant
before his second trial. And consequently, the Court does deny the Motion for
New Trial. [Footnote added.]
Mayberry’s confession to his participation in events on the night in question was newly
discovered evidence that was not cumulative and could not have been produced at trial with

reasonable diligence on the part of defendant. This Court held previously, however, that it could
not find that the trial court abused its discretion in denying defendant’s motion based only on
Mayberry’s confession. Ridenour’s testimony clearly corroborated defendant’s theory of the
case. The question is whether defendant was in possession of the Ridenour police report before
the second trial.
Although the credibility of defendant’s counsel’s testimony is diminished by his
professional record, this Court believes that several factors lend credence to counsel’s claim that
he did not have possession of the report. First, Ridenour was not called to testify even though
her testimony would have corroborated defendant’s statement to the police and could have served
as independent verification of a Mr. Deaton's potential testimony had defense counsel put him on
the stand.2 Second, neither the Waterford Police Department nor the prosecutor’s office ever
adequately followed up the potential charges against Beaumont and Mayberry, despite the
statements of defendant, Ridenour and Deaton which indicated that the two intended to rob the
victim on the night of the incident. At trial and at the evidentiary hearing the investigating
officers and the prosecutor respectively testified that they elected to undertake no further
investigation of these statements because this defense theory did not precisely coincide with the
information received and observed at the scene. However, the physical evidence so heavily
relied on by the police and the prosecutor’s office to discount the Beaumont and Mayberry theory
is far from dispositive. Third, during defendant's trial Detective Sergeant Bailey was asked who
he interviewed in connection with his investigation and he never mentioned Ridenour. And
finally, Ridenour was interviewed over two years after the incident. It is conceivable that this
last report did not find its way into the prosecutor’s possession.
Given these factors, this Court now finds that the introduction at trial of Ridenour's
statement and/or testimony, in combination with Mayberry’s jailhouse confession, would
probably have caused a different result. As noted by this Court previously, this conclusion is also
supported by the fact that the jury convicted defendant of the lesser crime of manslaughter rather
than the charged crime. However, such a conclusion does not automatically lead to a finding that
the trial court abused its discretion in denying defendant’s motion for a new trial. We are, in fact,
in a difficult position of having to consider this question given that the trial court had the better
opportunity to judge the credibility of witnesses at the evidentiary hearing. See, e.g., People v
Canter, 197 Mich App 550, 559-560; 496 NW2d 336 (1992). In light of this unenviable task, we
instead resolve the question whether defendant is entitled to a new trial on the following
alternative ground, understandably and appropriately raised by defendant.
In this appeal from the trial court's ruling following the evidentiary hearing, defendant
raises for the first time an additional claim alleging that if the prosecution did turn over the
Ridenour statement before defendant's third trial, his trial counsel was ineffective for failing to
2
Detective Sergeant Bailey testified at defendant's third trial that he took a report from a Mr.
Deaton and his wife on the night of the incident. Deaton informed Bailey that the couple lived
with Beaumont and that Beaumont and Mayberry discussed robbery plans the night of the
shooting. Defense counsel testified at the evidentiary hearing that although aware of this report,
he elected not to call Deaton because he was imprisoned at the time of trial and, in light of the
alleged absence of corroboration, would not have been a good witness.

call Ridenour as a witness. Assuming, for the purpose of resolving this issue, that the trial court
did not abuse its discretion and that the prosecution did provide the statement ahead of
defendant's third trial, we agree that during that proceeding defendant suffered ineffective
representation.
To prove a claim of ineffective assistance of counsel a defendant must show that
counsel’s performance fell below an objective standard of reasonableness and that the deficient
performance prejudiced the defense so as to deny the defendant a fair trial. Strickland v
Washington, 466 US 668, 687; 104 S Ct 2052; 80 L Ed 2d 674 (1984); People v Pickens, 446
Mich 298, 303; 521 NW2d 797 (1994). On the issue of deficient performance, a defendant must
overcome the strong presumption that counsel's assistance constituted sound trial strategy.
People v Toma, 462 Mich 281, 302; 613 NW2d 694 (2000). Prejudice denying a fair trial is
demonstrated when it may be concluded that there exists a reasonable probability that, but for
counsel's deficient performance, the result of the proceeding would have been different. Id. at
302-303.
The decision whether to call a witness is generally considered trial strategy. People v
Daniel, 207 Mich App 47, 58; 523 NW2d 830 (1994). In order to overcome the presumption of
sound trial strategy, the defendant must show that his counsel’s failure to call the witness
deprived the defendant of a substantial defense that would have affected the outcome of the trial.
Id. As implied by our preceding skepticism regarding the factors related to the issue of
possession of Ridenour's statement, we believe that effective representation of defendant ought to
have involved calling both Ridenour and Deaton as witnesses. Notwithstanding the apparent
determination by the police and prosecution that the information these individuals provided was
inconsistent with other evidence, and thus wholly irrelevant, we think it clear that their likely
testimony would have provided immense support for defendant's theory of the case. Again
assuming the possession of Ridenour's statement, we find it inconceivable that competent
defense counsel would elect not to present this significant evidence.
Accordingly, we conclude that defendant has defeated the presumption of sound trial
strategy. Toma, supra at 302. In addition we conclude that a deficiency of performance of this
magnitude prejudiced defendant. Id. at 302-303. Even without Mayberry's confession, which
was only later secured, we find it reasonably probable that the introduction of Ridenour's
statement and related testimony would have brought a different result in defendant's third trial.
Given this resolution, we need not address defendant’s additional claims.
Reversed and remanded for a new trial. We do not retain jurisdiction.
