Patterson v. State
Submitted by: Robert Amos Patterson, pro se.
Submitted by: Todd W. Hesel (Brian E. Frosh, Attorney General on the brief) all of Baltimore, MD, for Appellee.
Panel: Deborah S. Eyler, Arthur, James A. Kenney, III (Senior Judge, Specially Assigned), JJ.
Opinion by Arthur, J.Robert Amos Patterson, an inmate representing himself, appeals from the denial of a petition for writ of actual innocence, in which he challenged his 1993 convictions for first-degree murder and related handgun offenses. He raises a single question, which we have rephrased as follows: Did the circuit court abuse its discretion in denying the petition for writ of actual innocence on the ground that the unequivocal conclusion by State's expert on comparative microscopic matching did not create a substantial or significant possibility that the result at trial may have been different?1
Finding no abuse of discretion in the circuit court's denial of the petition, we shall affirm.
For background, we set forth part of the factual summary from this Court's unreported opinion in Patterson's direct appeal:
Patterson v. State , No. 1932, Sept. Term 1993, slip op. at 1-2 (filed July 28, 1994) (per curiam).
Although it was not an issue during Patterson's trial or direct appeal, the testimony of the FBI firearms examiner is now the subject of the instant appeal. That examiner, FBI Special Agent Joseph Williamson, testified, without objection, that the bullet recovered from the murder victim, as well as several other bullets recovered from the Annapolis crime scene, had been fired by the .38 caliber handgun that Officer Hyatt had recovered from Patterson, “to the exclusion of any other firearm in the world.”
During closing argument, the prosecutor relied upon Special Agent Williamson's unequivocal conclusion that the gun recovered from Patterson definitely fired the fatal shots. He told the jury that “the bullet was fired from this gun to the exclusion of all handguns ever made anywhere in the world”; that “[n]o other gun anywhere in the world could have fired those bullets except that one, that gun that was in the hands of Robert Patterson on July 17th”; and that the silver handgun, found in Patterson's possession eight days after the Annapolis murder, “definitely fired the bullets that killed Rudolph Holland[.]”
The prosecutor repeated these unequivocal assertions in the rebuttal phase of closing argument. There he told the jury that the “gun was analyzed by the F.B.I. and the bullets were tested by the F.B.I., and there's no doubt that the gun and the bullets that Mr. Patterson had in his hand were fired by that gun, the bullets that killed Mr. Holland.” He concluded with the assertion that “[y]ou've got Mr. Patterson in Washington, D.C., in possession of the gun that fired the bullets to the exclusion of all other guns in the world that killed Rudolph C. Holland.”
The jury found Patterson guilty of first-degree murder, use of a handgun in the commission of a crime of violence, and use of a handgun in the commission of a felony. The circuit court sentenced Patterson to a term of life imprisonment for first-degree murder and a consecutive term of 20 years' imprisonment for one of the handgun convictions.
In 1993, Patterson filed a motion for new trial on the ground of newly-discovered evidence—an affidavit, executed by an attorney who had investigated his case before trial, which contradicted the testimony of the arresting officer. The circuit court denied his motion, and this Court affirmed in an unreported opinion. Patterson v. State , supra , No. 1932, Sept. Term 1993. Later, Patterson unsuccessfully pursued post-conviction relief. Patterson v. State , No. 25, Sept. Term 1998 (filed June 25, 1998) (per curiam); Patterson v. State , No. 1355, Sept. Term 2010 (filed Mar. 24, 2011) (per curiam).
In 2013, Patterson, acting through counsel, filed a petition for a writ of actual innocence. That petition alleged that Patterson's trial had been tainted by the admission of testimony, from Special Agent Williamson, regarding the use of comparative bullet-lead analysis (“CBLA”), a technique that has been determined to be unreliable and inadmissible under the Frye-Reed test governing admissibility of scientific evidence in Maryland courts.
Clemons v. State , 392 Md. 339, 371, 896 A.2d 1059 (2006). The circuit court dismissed Patterson's petition without a hearing because a review of the trial transcripts led it to determine that Special Agent Williamson “never used CBLA to link the bullets” in Patterson's possession “to the bullets found at the crime scene.”
Patterson, acting through the same counsel, filed a second petition for writ of actual innocence, which is the subject of the instant appeal. In that petition, Patterson challenged the State's use of firearms identification evidence, which, as characterized by Special Agent Williamson, is “a comparative microscopic study that permits the identification of bullets and cartridge cases as having been ... fired by a particular firearm to the exclusion of any other firearm.”
“[C]omparative microscopic matching” “consists of attempting to identify the ‘toolmarks' impressed upon the bullet fragments and cartridge casings often recovered from a crime scene, in an effort to determine whether the toolmarks impressed upon the evidence could have been created by a firearm that has been connected to a suspect.” Fleming v. State , 194 Md.App. 76, 101, 1 A.3d 572 (2010). “The random imperfections in the bore of the firearm are theoretically unique to each firearm, and ‘the probability that another firearm would have identical bore imperfections is considered so remote that firearms identification examiners often conclude that a bullet has been fired from a particular firearm and could not have been fired by any other firearm.’ ” Id. at 103, 1 A.3d 572 (quoting Paul C. Giannelli & Edward J. Imwinkelried, Scientific Evidence § 14.03 (4th ed. 2007)). “In making the inquiry into the similarity or near-identity of toolmarks, a trained firearm toolmark examiner uses a ‘comparison microscope’ to compare spent ammunition components recovered from a crime scene with ammunition components fired from the candidate firearm.” Id. (citing United States v. Monteiro , 407 F.Supp.2d 351, 359 (D.Mass.2006) ). “Ultimately, the determination of whether a potential ‘match’ exists is made by a trained examiner using a split-screen microscope to simultaneously compare the toolmarks on the crime scene evidence against the toolmarks produced by a test round fired by the subject firearm.” Id. at 104, 1 A.3d 572 (citing Monteiro , 407 F.Supp.2d at 355 ).
Citing recent studies and court decisions that allegedly reveal the limitations of drawing the unequivocal conclusions that Special Agent Williamson expressed, Patterson claims to have identified newly-discovered evidence, which could not have been discovered through the exercise of due diligence in time to file a motion for new trial under Md. Rule 4–331(c), but which creates a substantial possibility that, had this evidence been admitted during his 1993 trial, a different outcome would have resulted.
The circuit court conducted a hearing on Patterson's petition. In a written opinion, the court concluded that the evidence would not have substantially affected the jury's verdict. Accordingly, it denied the petition.
Patterson noted this timely appeal.
A petition for writ of actual innocence, under Maryland Code , § 8–301 of the Criminal Procedure Article (“CP”), gives a convicted person “an opportunity to seek a new trial based on newly discovered evidence that speaks to his or her actual innocence [.]” Douglas v. State , 423 Md. 156, 176, 31 A.3d 250 (2011). Section 8–301 gives a person this opportunity by establishing the functional equivalent of a motion for new trial on the ground of newly-discovered evidence, but without the strict time limits imposed by Maryland Rule 4–331(c).
