The suspect behind the murder of a man who was dropped off at St. David’s Medical Center on Nov. 29 has been given additional charges, according to an affidavit released Dec. 14.

An arrest affidavit charges Jabari Mitchell, 25, in the murder of Trelin Reed, 21. In the affidavit obtained on Dec. 14, he was also charged with aggravated assault with a deadly weapon.

Police say they received multiple 911 calls shortly after 8 p.m. Nov. 29 to report shots had been fired at a convenience store along the southbound service road at 7200 North Interstate 35 (intersection of East St. Johns Avenue and I-35). Officers learned a white Ford SUV was seen speeding out of the parking lot, hitting at least two vehicles and a guardrail along the southbound frontage road.

The SUV arrived at St. David’s around 8:15 p.m., and the people in the SUV flagged down off-duty Pflugerville police officers working as security at St. David’s. Reed was pronounced dead around 8:30 p.m., and the other two people in the car were taken to South Austin Medical Center to be treated for their injuries.

The affidavit states police located “about 25” .223-caliber cartridge casings near the convenience store, and surveillance video showed possible muzzle flashes from a long black object that was protruding through a fence toward where the SUV had parked prior to the shooting. A relative of the victim told police Mitchell owned a semi-automatic rifle.

Police interviewed the other two people in the SUV with the victim, who said the victim was on the phone with Mitchell shortly before all three were shot. The two also stated Mitchell did not call back while they were on their way to the hospital.

Online records at the Travis County Jail state Mitchell was booked the evening of Nov. 30 with bond set at at least $500,000. APD released a booking photo of Mitchell on Dec. 8.
