SALISBURY — Forensic scientists with the N.C. State Crime Lab in Raleigh testified Tuesday about evidence that was examined from items seized in and near the scene of the 2014 murders of two Spencer men.

Antonio “Tony” Walker and his uncle James “Junior” Walker were shot to death inside the Spencer home owned by Angela White, the mother of Tony Walker, in what started out as an armed robbery. Several law enforcement officers testified that Kenneth Abel and his cousins Darius Abel and James “Mikey” Robinson intended to rob Tony Walker.

The three men knew Tony Walker was a drug dealer and believed he had large sums of money at his house, authorities said.

Kenneth Abel accepted a plea arrangement in September in exchange for testifying against his cousins. He testified earlier in the trial and is expected to serve more than 20 years in prison. He has not yet been sentenced.

Several items were collected at or near the crime scene including a du-rag, gloves, a gorilla mask and a cellphone. Earlier witnesses said the three men bought gorilla masks from the Halloween section of Walmart.

Terrence Snider, a former teacher and principal, testified that he recognized Darius Abel and James Robinson as former students and spoke to both men briefly the night they were at Walmart buying the masks. He saw a third man he did not recognize.

Surveillance video from Walmart, which was played for jurors, showed the three men in the store purchasing the masks.

Forensic scientist Matthew Wood told the court Tuesday that his expertise is in digital evidence, namely collecting and examining data from electronic devices. He was able to retrieve evidence from a cellphone that was submitted for analysis, he said.

Wood said he essentially performed a data dump to extract a call log, text messages, pictures, emails and the like from the phone. One email was in the name of Mike Gunz, who received a confirmation for an Amtrak ticket purchase.

The last text message from the phone was sent Oct. 8, 2014, to a woman with a photo attached. The picture was a selfie of James Robinson taken in the mirror holding the cellphone that was collected as evidence.

The last call the phone logged was to a number with the contact listed as Larry. Testimony earlier in the trial was that the men got Larry Hairston to drive for them because Kenneth Abel’s license had been suspended.

The phone was last used at 10:11 p.m., when a call was made and missed, Wood testified.

According to Assistant District Attorney Paxton Butler, authorities believe James Robinson was trying to call Hairston after the murders to meet the three cousins and drive them from the scene.

Forensic scientist Tricia Daniels testified that she tested a mask, a glove and a du-rag. There was no blood on the mask or du-rag, but blood was found on the glove. The glove also contained a hair-like substance believed to be from the mask, Daniels said.

According to the scientists, there was no DNA or fingerprints on the cellphone. Daniels said she did not test the cellphone, but it was sent to another lab scientist for testing.

In addition, a pair of Reebok high-tops were swabbed for blood, but none was found.

Jurors also heard from former Spencer Police Department Detective Nicholas Pacilio about what evidence was collected and his role in the investigation. Pacilio was the lead on the investigation. He went to Walmart to speak with the loss prevention manager who discovered the surveillance video and purchase logs of the gorilla masks.

The trial resumes at 9:30 a.m. Wednesday.
