Records: Boy killed during fight over teen's child

LOS LUNAS, N.M. (AP) — Court documents say a 15-year-old New Mexico boy accused of killing his 12-year-old friend struck him following an argument over the teen's daughter.

The arrest warrant affidavit, first obtained by KRQE-TV, says the 15-year-old suspect hit Alex Madrid, of Albuquerque, on the left side of his head, then placed him under a mattress in a field west of Los Lunas.

The documents mention the teen's daughter but don't list her age.

Authorities say Madrid's body was found Tuesday.

The suspect told deputies Madrid had tried to stab him with a screwdriver. He has been charged with first-degree murder and tampering with evidence.

The teen's attorney, Cindy Mercer, didn't immediately return a phone message from The Associated Press.

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