Man shot to death in River West gym, person in custody

A person of interest in a fatal shooting in the gym of a River West apartment building Wednesday night surrendered to police early Thursday.

Darrin Joss, 45, was shot in the head about 7:06 p.m. in the eighth-floor gym of the apartment building at 555 W. Kinzie, according to Chicago Police and the Cook County medical examiner’s office.

Joss, who lived on the same block, was taken to Northwestern Memorial Hospital, where he was pronounced dead at 7:48 p.m., according to the medical examiner’s office.

Late Wednesday, Chicago Police Department spokesman Anthony Guglielmi tweeted that the shooting was an “isolated incident” and that detectives “know who [the shooter] is and are actively looking.”

A person of interest in the shooting arrived at CPD Headquarters about 3:30 a.m. Thursday and surrendered, according to a statement from police. No charges had been filed as of 12:30 p.m.

Alexa Regiman, who lives in the building, told reporters she was working out while listening to music when she felt the ground shake.

“The second time, I was like ‘Something’s not right’,” she said. After she felt the thuds, she looked to her left and saw a man—who had been using a treadmill—lying on the ground covered in blood.

The shooter was a man in a wheelchair whom she had seen in the building before, she said.

“I just moved here,” she said. “I’m still thinking this is a safe area, but the fact that it happened right behind me . . . what if that were me?”

SWAT teams were called to the building, but residents were let back into their units about an hour after the shooting.

Once told of the shooting, several residents were shocked that it took place in an area that normally sees little gun violence.

“You’re s——- me,” one man said.
