(CBS) - A 15-year-old boy remained in custody Sunday night as detectives tried to piece together what led to the shooting of five people, including three young 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, said Lt. Sid Covington, a Bernalillo County sheriff's spokesman.
Detectives did not immediately release the victims' names, but 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.
"Chaplin 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.
Covington said detectives were working to positively identify the five victims as well as the teenager's relationship to them.
"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," Covington said.
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.
