STATE OF WASHINGTON, ) No. 40166-9-III ) Respondent, ) ) v. ) UNPUBLISHED OPINION ) LUIS GUADALUPE RODRIGUEZ- ) PEREZ, ) ) Appellant. )

LAWRENCE-BERREY, C.J. — The State charged Luis Rodriguez-Perez and William

Martinez of murder in the second degree, either as principal or accomplice. Witness and

video evidence firmly established that one of the two was the shooter and the other was

the accomplice. After Martinez testified that Rodriguez-Perez was the shooter, the State

changed its theory and argued that Rodriguez-Perez was the principal. A jury convicted

both of murder, Rodriguez-Perez appealed his conviction, and we affirmed.

Thereafter, and pursuant to RCW 10.73.170, Rodriguez-Perez moved the trial

court to allow postconviction DNA testing of swabs of his hands taken after the shooting

and of a shell casing recovered from the scene. He argued the swabs of his hands would

show the absence of gun powder, which would establish he was not the shooter, and the

shell casing would not contain his DNA, further establishing he was not the shooter. The No. 40166-9-III State v. Rodriguez-Perez

trial court denied Rodriguez-Perez’s motion, and he appealed the denial to this court.

We note that postconviction testing for gun powder is not permitted by

RCW 10.73.170. We conclude that a favorable DNA test of the shell casing would not

establish Rodriguez-Perez’s innocence on a more probable than not basis. Rather, in the

context of the evidence at trial, a favorable DNA test, at most, would establish only that

Rodriguez-Perez was an accomplice to murder. Because Washington law treats

accomplice liability the same as principal liability, we affirm the trial court’s denial of

Rodriguez-Perez’s motion for postconviction DNA testing.

FACTS

Background

In 2014, Luis Rodriguez-Perez, William Martinez, and Efren Iniquez attended a

concert. State v. Rodriguez-Perez, 1 Wn. App. 2d 448, 452, 406 P.3d 658 (2017).

Martinez saw that Rodriguez-Perez was carrying a firearm in his waistband, which was

the same gun he normally carried. Id. Rodriguez-Perez drove his friends to the concert.

Id. As the trio approached the concert venue, they noticed security staff using a wand to

scan entrants for firearms. Id. Rodriguez-Perez walked away from the entrance, and

minutes later, returned and entered the venue. Id.

During the event, approximately 40-50 people left the venue, and a number of

them began to fight. Id. Surveillance video showed Martinez running toward the parked

2 No. 40166-9-III State v. Rodriguez-Perez

car with Rodriguez-Perez walking behind. Id. The video showed the two walking back

toward the fight minutes later. Id.

At the fight, Da’Marius Morgan punched Justin Navarro. Id. at 453. The two

individuals were arguing when either Martinez or Rodriguez-Perez fired at least three

shots at Morgan. Id. One of the bullets struck Morgan’s heart, which led to his death.

Id. A bystander was shot in the leg but was unable to identify the shooter. Id.

The security guard at the event witnessed the shooting. Id. He saw one of three

men standing near his truck shoot a gun at Morgan. Id. The security guard saw Morgan

fall to the ground and witnessed the three men flee toward an alley. Id. The three men

later were identified as Rodriguez-Perez, Martinez, and Iniquez. Id. A surveillance

video showed Rodriguez-Perez tossing an object into a bush. Id.

Law enforcement arrived at the scene and quickly went to the alley. Id. at 453-54.

The officers saw people yelling and running toward a bush. Id. at 454. Rodriguez-Perez

and Martinez were hiding behind the bush, and the officers pulled them out from behind

the bush and arrested them. Id.

Two witnesses identified Martinez as the shooter. Id. Another witness said

Martinez was the shooter but then said it was possible Rodriguez-Perez could be the

shooter if he had been wearing a hat and later removed it. Id.

3 No. 40166-9-III State v. Rodriguez-Perez

The officers did not find the gun at the time of the arrest. Id. However, a man

walking his dog the next morning found the weapon where the surveillance video showed

Rodriguez-Perez tossing it. Id. Forensic tests established that the gun was the murder

weapon. Id. In addition, the gun’s magazine had a fingerprint that matched Rodriguez-

Perez’s fingerprint. Id.

DNA Testing

An evidence technician used buccal swabs to obtain DNA samples from both

Rodriguez-Perez and Martinez. The buccal swabs were used as reference samples to

compare with DNA found on the trigger, grips, slide, and magazine lips of the murder

weapon. Before the DNA test of the weapon was conducted, the deputy prosecutor

learned that the DNA found on the gun would be consumed during testing. The court

granted the State’s motion allowing the crime laboratory to consume the entire quantity

of the DNA on the gun. The DNA testing of the gun showed a profile mixture of at least

four individuals. Because the profile was complex, the DNA testing did not include or

exclude either suspect.

The State charged Rodriguez-Perez and Martinez as principals and accomplices

for the murder of Morgan. The State also charged both as principals and accomplices for

assault of the bystander. Initially, the State sought to prove that Rodriguez-Perez was the

accomplice. But after Martinez testified that Rodriguez-Perez was the shooter, the State

4 No. 40166-9-III State v. Rodriguez-Perez

argued that he was the principal. Following trial, the jury convicted both men of the

murder yet acquitted both of assault. We later affirmed Rodriguez-Perez’s conviction.

Thereafter, pursuant to RCW 10.73.170, Rodriguez-Perez filed a motion for DNA

testing of the swabs of his hands and a shell casing found at the scene. In his motion, he

requested that the swabs of his hands be tested for gunshot residue or any other DNA,

and the shell casing be tested for DNA. The State opposed the motion. At the hearing,

Rodriguez-Perez argued that further DNA testing would show he never held the gun,

which would clear him of liability as a principal.

In its written conclusions denying the motion, the trial court explained:

5. DNA evidence presented at trial was not conclusive and did not support a conviction or acquittal; but the jury verdict reflects that it relied on other evidence which was sufficient to support Mr. Rodriguez-Perez’ conviction. 6. DNA taken from the firearm that was used to kill the victim showed a mixed sample which came from more than one contributor and was not used to specifically identify the defendant as the murderer. 7. Testing of DNA samples taken from the defendant would not impact the verdict or establish innocence because there was not any DNA evidence used to identify the defendant.

Rodriguez-Perez appeals the denial of his motion to this court.
