New Mexico teen indicted in 12-year-old's killing

LOS LUNAS, N.M. (AP) — A 15-year-old New Mexico teen accused of killing his 12-year-old playmate has been indicted on a murder charge.

A Valencia County grand jury indicted the teen on charges of first-degree murder and tampering with evidence.

Thirteenth Judicial District Attorney Lemuel Martinez said last week that he intends to try the 15-year-old as an adult.

An arrest warrant affidavit says the teen hit Alex Madrid, of Albuquerque, on the left side of his head, then placed him under a mattress in a rural field outside Los Lunas.

The teen told investigators he hit Madrid in self-defense because Madrid tried to stab him with a screwdriver.

Under New Mexico law, the state can charge minors as adults only if they are at least 14. The Associated Press doesn't typically identify juveniles charged in crimes.
