PHOENIX - A man has been arrested in connection with an attack in Phoenix that left one priest dead and another seriously injured.
Phoenix police confirm Gary Moran was taken into custody Sunday night in connection with the death of Rev. Kenneth Walker and beating of Rev. Joseph Terra.
Sources said DNA at the scene linked Moran to the attack.
The 54-year-old is facing charges of first degree murder, attempted murder, armed robbery, theft, and burglary.
Phoenix police said the attack is not Moran's first run-in with the law. In 2005, he pleaded guilty to aggravated assault with a deadly weapon and burglary charges.
He was released from prison on April 26, 2014 and had been living on the streets and in homeless shelters, Chief Daniel Garcia said.
I can confirm @phoenixpolice has made an arrest in Mother of Mercy Mission homicide. Further details will be provided late morning.— Steve Martos (@SgtMartos) June 16, 2014
Walker was shot and killed in the Wednesday night attack. Terra suffered blunt force trauma and was taken to a local hospital with serious injuries. On Monday morning, he attended mass held in Walker's honor.
Sources tell ABC15 the scene at the Phoenix church was "gruesome." The attack occurred around 9:30 p.m. on Wednesday, according to police.
Police are unsure of a motive in the violent attack at the Mother of Mercy Mission. A vehicle belonging to Walker, who died at a hospital late Wednesday, was found abandoned a few blocks from the church.
Police believe Moran took the 2003 Mazda and left it behind after the crime.
Phoenix Mayor Greg Stanton said the city was shocked and saddened by the incident.
The two priests lived at the church, located along a gritty stretch of downtown Phoenix near the state Capitol. Terra, 56, served as pastor and Walker, 28, as assistant pastor.
