The man was found dead Saturday afternoon inside his apartment in the 12700 block of Kiowa Road.
Investigators were led to a 16-year-old female who knew the victim.
They said the suspect was at the victim's home and they got into some kind of argument and she stabbed him multiple times. She then left in the victim's car.
The juvenile suspect, whose name was not released, was arrested Sunday and booked at Juvenile Hall for murder.
Neighbors and friends said the victim, Willie Hunter, 79, was a reverend at United Church in Christ of Apple Valley.
"He was a stand-up man," said Anthony Brandon. "A real man of God. Loved the word, loved the Lord. Had no enemies. Was always nice to everybody. Give you the shirt off his back."
