TULSA -- In a 2News exclusive, the mother of a Tulsa teenager shot in the head, plans to take her son off life support Saturday.
18-year-old Keondrea Love was shot execution style at North Tulsa's Apache Manor apartment complex Thursday night.
Tulsa Sgt. Dave Walker said the suspect, 25-year-old Keith Bernard Mack, turned himself into the Tulsa County Jail with a lawyer Friday night.
Tulsa police issued an arrest warrant for Mack earlier Friday.
Love's mom, Lola, said her son went to buy a snack when two guys walked up to him. In the middle of talking, Love walked away. That's when Mack shot him execution style, according to police.
"I've been wiping his face. You just don't know what the doctors are going to come in and say next. To hear the doctors say 'he's gone. We did all we can do, it's over with.' That's horrible" said Lola.
Doctors are harvesting Keondrea's organs to donate them.
"I have to go pick my son out a casket. Not a pair of shoes, not a suit, or helping him find a car. A casket. What would make someone want to take someone else's life? I really want to know what's the reason."
Detectives have yet to determine a motive, however investigators say Love and Mack knew each other.
The Tulsa Police Department homicide Unit along with agents with the Northern Oklahoma Violent Crimes Task Force worked to identify Mack.
