Oklahoma City prosecutors charged 28-year-old Chance Alan Wilson of Purcell with the murder of his own sister.
Court documents reveal Chance gave 16-year-old Saleda Wilson a massive dose of methamphetamine and then left her with friends.
Saleda's family was too heartbroken to talk on camera. But her mother tells News 9's Adrianna Iwasinski by phone that she loved her more than anything. Now with her daughter gone, and her son in jail, she feels she's lost everything.
Saleda's father found her body inside the northeast Oklahoma City home back on July 7, but her brother was not charged until August 14.
Oklahoma City police say these kinds of cases often times are very convoluted.
"It takes investigators a lot of times sometimes to sort through everything," said Msgt. Gary Knight. "And ultimately follow the evidence and come to the proper conclusion."
According to Court papers, Chance Wilson brought his sister Saleda to a home in the 1400 block of North Court in Oklahoma City the night of July 6, in order to do drugs with two friends.
One of those friends claim he witnessed Chance "shoot up" Saleda with 20 units of meth that night and then give her 30 more units in each arm the next morning.
Court papers go on to say once Chance left, the friend said Saleda started "freaking out." The friend called Chance, who said to put Saleda in the shower, and to run some water on her.
The friend said he did, and that the two fell asleep. He woke up to someone knocking on the door, but could not get Saleda to wake up.
He then called Chance, who reportedly told him to get out of the house, because his father was coming back with police.
Prosecutors tell News 9 it is rare for them to charge someone with murder for injecting someone with an overdose of drugs. But they felt in this case it was justified.
Wilson was already in the McClain County Jail. The undersheriff says he is accused of embezzlement and jumping bail.
He is expected to be transferred to the Oklahoma County jail and be arraigned by an Oklahoma County judge on the murder charge this week.
