A man in another vehicle was shot in the head, and later ended up at the Holiday Inn Express a few blocks away. The car had at least six bullet holes in the windshield.

Officers from Crestwood, Alsip, and the Cook County Sheriff’s office responded to the shooting.

An employee at the hotel said five people, including the victim, came into the hotel. The victim had been shot in the head, and was taken to the hospital.

Alicia Renteria was heading to work when the Toyota pulled up to the hotel, and she helped the victim before paramedics arrived.

“The one that was shot, they just brought him towels and stuff like that to keep him warm,” she said. “They were just looking for help, that’s all, but we were able to help them, keep them here and stuff, but we didn’t know what was going on.”

The victim’s condition was not available Monday morning.

Renteria said police questioned several people who were in the car with the victim.

“The police stayed here for about an hour, interviewing them, and they were saying that they were going to eat at the restaurant, and then all of a sudden somebody started shooting, and that’s when they tried to get away from them, and came over here,” she said.
