Parker was arrested Thursday at 6:45 a.m., just over three hours prior to his death, in connection with the alleged abduction of his girlfriend in July 2022.
Police claimed that Parker forced the woman into a vehicle against her will outside their residence on the northwest side of town. They were alerted to the situation by the victim's family and friends after a live Instagram video allegedly showed Parker pointing a gun at her.
The victim was later found safe.

Parker was charged with armed kidnappings involving a gun in that case.
Searches for contraband and weapons happen at holding facilities, according to an MPD standard operating procedures document. More extensive searches of someone in custody must be approved by a watch commander.
MPD says the department's internal affairs bureau is investigating Parker's death.
