Los Angeles County Sheriff's Department deputies were called to the home of June Collins about 5:30 p.m. for a welfare check, after neighbors reported she hadn't been seen in about a week, according to a department news release.

When deputies entered the home they smelled a strong odor and discovered two bodies in advanced stages of decomposition, according to Lt. John Corina. 

Investigators found a woman, later identified as Collins, in one room, and Bustamante in another.

Both victims were pronounced dead at the scene at 6:16 p.m., Colllins was found in pool of blood with stabs or cuts to her neck, according to coroner's records. The teen was also found in a pool of blood, with stab wounds, according to coroner's records. 

As they searched the property, investigators discovered that Collins' car was missing. Deputies found the Toyota Camry the next day about noon in the 12100 block of Magnolia Street in El Monte. 

Corina said Collins lived with her adult son, but investigators said he was in custody and not at home when the two were killed.
