ALBUQUERQUE, N.M. (AP) — A 15-year-old boy remained in custody Sunday night as detectives tried to piece together what led to the shooting of his parents and three of their children who were found dead in a New Mexico home.

The teenager was arrested on murder and other charges in connection with the shootings, which happened Saturday night at the home in a rural area southwest of downtown Albuquerque, the Bernalillo County Sheriff's Department said.

Authorities identified the victims late Sunday as Greg Griego, 51, his wife Sara Griego, 40, and three of their children: a 9-year-old boy, Zephania Griego, and daughters Jael Griego, 5, and Angelina Griego, 2. The suspect was identified as Nehemiah Griego.

Word of the shootings traveled quickly through the law enforcement community, and officials began offering their condolences for Greg Griego, a spiritual leader known for his work with firefighters and the 13 years he spent as a volunteer chaplain at the county jail.

"Chaplain Griego was a dedicated professional that passionately served his fellow man and the firefighters of this community," Fire Chief James Breen said in a statement. "His calming spirit and gentle nature will be greatly missed."

Jail Chief Ramon Rustin said Griego was instrumental in the creation of the Metropolitan Detention Center's chaplain program and worked to get inmates integrated back into the community.

Griego also was a former member of the pastoral staff at Calvary, a Christian church in Albuquerque. As part of his work there, he oversaw the Straight Street program for jail inmates.

Authorities said each victim suffered more than one gunshot wound, and several guns were found at the home, one of which was a semi-automatic military-style rifle. Investigators were trying to determine who owned the guns.

"Right now we're to the meticulous points of processing the scene and collecting physical evidence, and this is a vast scene with a lot of physical evidence," sheriff's department spokesman Lt. Sid Covington said.

Authorities declined to release details of any conversation that the 15-year-old had with investigators, but they said he was the Griegos' son. The sheriff's office said he is charged with two counts of murder and three counts of child abuse resulting in death.

The sheriff's office said it wouldn't release any further information about the case until Sheriff Dan Houston holds a news conference Tuesday morning. Continued...
