Police in the border city of Tijuana have arrested a man in the killing of a San Diego boy who went missing over the weekend.
Baja California state prosecutors say in a statement that 19-year-old Jose Ruben Quintero Mariscal has confessed to strangling 8-year-old David Lizarraga Gomez with a shirt.
Prosecutors say Quintero Mariscal lived next door to the boy and the he lured him to his house to sexually abuse him. They say the boy was killed shortly after being abducted Saturday.
Police found his body Monday stuffed in a suitcase on an empty lot near his home.
Prosecutors said Tuesday they found child pornography in Quintero Mariscal's home.
It wasn't immediately known if Quintero Mariscal had a lawyer.
