Bernalillo County Sheriff's Deputies have arrested a 15-year-old boy in connection with the shooting deaths of five people on Saturday night in a private home south of Albuquerque.

Updated at 1:30 p.m.: Deputies have identified the teen shooter as Nehemiah Griego.

Updated at 9:00 p.m.  Authorities have identified the victims as Greg Griego, 51; his wife Sara Griego, 40; and three of their children: Zephania Griego, 9, Jael Griego, 5, and Angelina Griego, 2.

Deputies say each victim appears to have been shot multiple times. Numerous weapons were found inside the home on the 2800 block of Long Lane, SW.

Sheriff Dan Houston has not released a criminal complaint and would not speculate on Griego's motive, nor elaborate on where and when he was arrested.

Investigators also were seeking to determine who owned several guns that were found at the home, one of which was a semi-automatic military-style rifle.

Griego has been booked on two counts of murder and three counts of child abuse resulting in death.

The Albuquerque Fire Department morns the senseless loss of one of our spiritual counselors, Greg Griego.  Chaplin Griego was a dedicated professional that passionately served his fellow man and the firefighters of this community.  His calming spirit and gentle nature will be greatly missed.  Our thoughts and prayers go out to Greg's extended family.
