OKLAHOMA CITY (AP) ó A June 21 trial date has been scheduled for a pharmacist who has been charged with first-degree murder in the death of a teenager.

Oklahoma County District Judge Tammy Bass-LeSure set the date Wednesday for Jerome Ersland after speaking with Erslandís attorney, Irven Box, and District Attorney David Prater.

Ersland fatally shot 16-year-old Antwun Parker, who was unarmed, on May 19 at the Reliable Discount Pharmacy in south Oklahoma City.

Prosecutors alleged that Ersland went too far when he shot Parker five more times after knocking him unconscious with a shot to the head.

Ersland said he was defending himself and two female employees, and he thought Parker had a gun.

Another robber who was armed fled the drugstore but was later caught.
