An Oak Lawn man who was found unconscious at the door of his home last week died Monday morning, according to the Cook County Medical Examiner’s office.

Terrence Reichert, 51, died at 10:29 a.m. at Advocate Christ Medical Center in Oak Lawn, according to the medical examiner’s office. His autopsy is set for Tuesday.

On Sunday, his family was searching for answers, believing he was attacked and wondering about who may have attacked him and why. But police also are investigating the possibility he may have been injured in a fall, police said.

“A lot of rumors are flying around and we’re tracking them down,” Oak Lawn Deputy Police Chief Mike Kaufmann said on Monday. “That’s where we’re at right now.”

The man’s brother said his family didn’t want to comment.

“We need to heal as a family and if we need help, we’ll reach out to people,” his brother said.

Previously, he called his brother’s death “very bizarre,” and suggested that someone may have attacked him in the driveway of his own home.

The man, a carpenter, shot pool until about 1 a.m. Wednesday morning at Town Lounge in Hometown. Another brother then drove him to his home in the 11000 block of Komensky. The man’s girlfriend found him lying unconscious at his front door about five hours later, his brother said.

The man was taken to Christ Medical Center. He initially was able to communicate, but later experienced a series of strokes that led to emergency brain surgery, according to his brother.

The man had bruises on much of his body, but his injuries were limited to his head, his brother said.

Robbery does not appear to be a motive. The man’s wallet and money were found in his pockets and a gold chain remained on his neck, his brother said.

Oak Lawn police are asking anyone with information on the case to call 708-422-8292.
