An autopsy released Wednesday for a Chattanooga businessman killed downtown in September shows he was intoxicated at the time of the shooting.
Chris Wright, 38, was shot in the head after a short interaction outside Patten Towers on Sept. 28.
The man arrested in connection with the shooting, 57-year-old Darryl Roberts, was arrested later that day and remains at the Hamilton County Jail on a $5 million bond, according to jail records.
Wright had a blood alcohol concentration of .201% at the time of his death, the autopsy showed. An odor of alcohol was present in the gastrointestinal tract, according to the report.

The legal limit to drive is .08%, and enhanced penalties for drunk driving start at .2%. According to data from the University of Tennessee at Chattanooga's Center for Wellbeing, a man of Wright's size would have to drink around 10 to 11 standard drinks to reach a level of .2%.
Blood alcohol poisoning can set in around .3% to .4%, according to the Cleveland Clinic.
Chattanooga Police Detective James King, speaking at Roberts' preliminary hearing Monday, said Wright had driven to downtown.
Wright reportedly appeared "drunk and looking tough" when he approached Roberts and others sitting outside Patten Towers, witness Bryant Houston said at the hearing Monday.

Security footage played during that hearing showed Wright walking south on Georgia Avenue between Pickle Barrel and Patten Towers, then stopping in front of the group around 11:45 p.m.
A witness said he told Wright several times to "keep it moving" but said he didn't remember what else was said.
The video has no sound because Chattanooga's public safety cameras don't record audio, according to an email from Sgt. Victor Miller.
King, the detective, said when he asked Roberts what was said before the shooting, Roberts told him to ask the victim.
Roberts' case was sent to a grand jury, where official criminal charges will be decided.
Court records show Roberts has an extensive criminal history, with more than 60 arrests in Hamilton County going back to the 1990s. He had felony convictions that should have barred him from having a gun, according to court records. His arrests were related to charges including assault, aggravated robbery and domestic assault, records show.
Wright's autopsy showed his death was ruled a homicide by gunshot to the head. The shot, from intermediate range, entered his left central forehead, the report said.
The medical examiner recovered a medium-caliber jacketed hollow-point bullet from the brain and found skull fractures and brain lacerations, according to the report. The bullet was turned over to investigators, the report said.
In response to the shooting, Chattanooga Mayor Tim Kelly announced plans to add police officers downtown, enhance the city's surveillance camera network and form a public safety commission to recommend policies. Deputies from the Hamilton County Sheriff's Office are also working overtime shifts to add coverage downtown.
