PATRICK MARQUISE NAPOLEON, Appellant,
v.
THE STATE OF OKLAHOMA, Appellee.

O P I N I O N

ROWLAND, JUDGE:

¶1 Appellant Patrick Marquise Napoleon appeals his Judgment and Sentence from the District Court of Tulsa County, Case No. CF-2017-2208, for Assault and Battery with a Deadly Weapon, in violation of 21 O.S.2011, § 652

(1) whether the district court erred in denying his motion to exclude DNA evidence because the DNA was contaminated;
(2) whether the district court erred in denying his motion to exclude DNA evidence because the probabilistic genotyping testing that was conducted was not sufficiently reliable;
(3) whether the district court improperly limited his defense;
(4) whether the district court admitted prejudicial hearsay evidence;
(5) whether he was denied effective assistance of counsel;
(6) whether he was denied a fair trial because of the prosecution's failure to disclose exculpatory evidence; and
(7) whether an accumulation of error deprived him of a fair trial.

¶2 We find relief is not required and affirm the Judgment and Sentence of the district court.

FACTS

¶3 This case involves the ruthless, near-fatal stabbing of Nancy Johnson Jones outside Hillcrest Medical Center in Tulsa on April 6, 2017. Jones had taken a quick break from visiting her stepmother to get a snack at a nearby QuikTrip before nightfall. As she approached the hospital's north entrance, her attacker came up behind her, plunged a serrated boning knife into her neck, and fled on foot towards the parking garage without taking anything from her. The disputed issue at trial was the identity of the perpetrator.

¶4 A hospital employee witnessed the attack from near the north hospital entrance. She identified Napoleon as Jones's attacker at trial. She described the attacker to police at the scene, explaining he was wearing camouflage pants and something white on his forearm. Another hospital employee, who was in her car in the parking garage, identified Napoleon as the person she saw wearing camouflage pants hurriedly putting objects in a parking garage trashcan and dashing up the stairs. Hospital security apprehended Napoleon on the street not far from the parking garage within fifteen minutes of the attack. Based on interviews with the employees, police found the bloody knife used in the stabbing in the parking garage trashcan along with the white sock the attacker wore over his hand. Police also found a pair of camouflage pants in a nearby stairwell. The employee in the parking garage testified she saw a man with the same build as the man she had seen in the camouflage pants running down the adjacent stairwell wearing black pants. She believed the man in the camouflage pants and black pants were the same person. When police arrested Napoleon, he was wearing black thermal pants.

¶5 DNA analysis using random match probability on the sock and camouflage pants performed by the Tulsa Police Department's forensic lab could neither exclude Napoleon nor include him because the DNA collected from both items was a mixture of two or more persons. After Napoleon's first trial ended in a mistrial, the State enlisted Sorenson Forensics to conduct probabilistic genotyping testing via the software program BulletProof. The software program analyzed the raw data from the previously indistinguishable DNA mixtures with Napoleon's known DNA profile to calculate a ratio of the likelihood his known profile would be included within the mixture and, if so, the approximate contribution proportion of his sample within the mixture. The results showed that it was far more likely that Napoleon's DNA was a major contributor to the mixture of DNA on both the sock and pants and that his DNA exceeded 50% of both mixtures.

¶6 Napoleon maintained his innocence and offered an alibi.

1. DNA Contamination

¶7 Napoleon claims the district court erred in admitting, over his objection, some of the prosecution's DNA evidence. He challenges the probabilistic genotyping testing conducted by Sorenson Forensics, using the software program BulletProof, on the DNA mixture profiles collected from the attacker's sock and camouflage pants. He maintains the DNA evidence obtained from those items was too contaminated for the results of testing to be reliable and relevant. According to Napoleon, ample evidence suggested that the DNA obtained from the sock and camouflage pants had been contaminated "both by possible third-party contamination" or "cross-contamination of evidentiary items with Mr. Napoleon's DNA as a result of evidence mishandling at Mr. Napoleon's first trial." We review the district court's ruling admitting the evidence for an abuse of discretion. Jackson v. State, 2024 OK CR 11548 P.3d 473Posey v. State, 2024 OK CR 10548 P.3d 1245cert. denied, 145 S. Ct. 1142 (2025).

¶8 Any contamination from the handling of the sock and pants at Napoleon's first trial did not render the probabilistic genotyping results unreliable. Before trial, Napoleon unsuccessfully sought to exclude the probabilistic genotyping test results, arguing, among other things, that contamination of the sock and pants rendered the results unreliable. The district court considered Napoleon's motion in conjunction with a Daubert hearing. The State presented the testimony of Kent Harman, who was recognized as an expert in probabilistic genotyping without objection. He explained that probabilistic genotyping accounts for multiple contributors and explained how it does so and how "contamination" from others does not render its results unreliable. Napoleon offered nothing to contradict the expert's conclusions and methodology.

¶9 Based on this record, the district court did not abuse its discretion in admitting the probabilistic genotyping results to assist the jury in assessing the otherwise ambiguous DNA evidence. The challenged testing supported a finding that Napoleon was a contributor of the DNA on the sock and pants. Any possible contamination was factored into the results and affected only the weight of the evidence rather than its admissibility. See State v. Hovet, 2016 OK CR 26387 P.3d 951 Fixico v. State, 1987 OK CR 64735 P.2d 580

2. Reliability of Probabilistic Genotyping

¶10 Napoleon claims the district court erred by overruling his motion to exclude the probabilistic genotyping software program (PGSP) results from BulletProof used to analyze the DNA mixtures collected from the attacker's sock and pants. He contends that BulletProof and the methodology it employs are insufficiently reliable to pass muster under Daubert and Taylor v. State, 1995 OK CR 10889 P.2d 319Daubert analysis for novel scientific evidence in Oklahoma criminal cases). de novo. Bosse v. State, 2017 OK CR 10400 P.3d 834Daubert.
