The 39-year-old Emiel Lamar Hunt was indicted on Tuesday with the death of Trinity Love Jones. The body of Trinity was found on March 5 in a light brush near a riding trail in Hacienda Heights.
Authorities believe Hunt killed Trinity on or about March 1, Los Angeles District Attorney's Office said. Officials have not published a possible motive.
The girl's body was found, head and torso protruding from a partially zipped duffel bag.
Hunt is allegedly the friend of Trinity's mother, said the Sheriff Department in Los Angeles.
When Hunt was tried on Tuesday for murder charges, Trinity's father, Antonio Jones, stood up and called him.
"They killed my daughter!" Jones screamed: During the hearing, the father cried and clenched his fists.
Hunt's bail was priced at $ 2 million, and his indictment continued until April 16. A public defender is appointed to his office.
If Hunt is convicted of murder, he could face life in jail.
The authorities have arrested a second person, but information about this "interested person will be held back for further investigation," the sheriff's department said.
