Anthony Garcia, 32, and Summer Stephens, 37, were arrested this week, sheriff's officials said on Thursday. The identity of the boy and circumstances surrounding his arrest were withheld because he is a minor. Investigators did not disclose the relationship among the three.
According to authorities, police responding to the scene Tuesday night found Garcia with a head wound, outside of an abandoned home on the 20000 block of Mariposa Road. The victim, whose identity was not immediately released, was found inside the home.
How the victim died remains under investigation.
