A man escaped police custody Wednesday afternoon while being treated at a Greenwood hospital, according to police.

Alexander Kade Lanier was being treated Wednesday at Self Regional Medical Center after he was arrested by Greenwood police in connection with a burglary and domestic violence investigation from Tuesday night, Greenwood Police Department Public Information Officer Jonathan Link said.

At about 4:40 p.m. Tuesday, Lanier eluded police, who minutes later discovered he was no longer in his hospital room, Link said. He did not have enough details to say how Lanier escaped police custody or surveillance, but officers have been searching near Self since then to find him.

“I can’t think of the last time we had somebody escape our custody like this, but it’s very unfortunate,” Police Chief T.J. Chaudoin said. “There’s a lot of questions to be asked like why he wasn’t in handcuffs, why he wasn’t in leg irons. There’s several questions that have to be asked to figure out why he wasn’t restrained.”

Chaudoin said Lanier was being treated at the hospital after telling officers he had consumed an illegal substance. Hospital staff members were monitoring him after treatment, and Chaudoin said one sworn officer was assigned to watch Lanier when he escaped. He said an investigation is underway into how Lanier escaped and whether department policy was followed.

Lanier was last seen wearing a red hoodie and gray shorts. Chaudoin said after Lanier’s escape, he stole a vehicle from someone he knew who lived on Woodrow Avenue. Police are working with hospital security staff to determine his whereabouts and find the stolen car. Chaudoin said all investigators and his administrative staff are out searching, along with the SWAT team and police department’s K9 unit.
