A man on parole for drugs was arrested in the death of a 22-year-old woman found shot to death Monday in a Gold Coast hotel.
Police arrested the 28-year-old Chicago man late Tuesday at his Humboldt Park home, according to the Chicago Tribune. The publication says the suspect left his cell phone behind in the room.
Police confirmed to NBC Chicago that several people are still being interviewed and the investigation is ongoing.
Brianna Gardner from Dallas was found at 10 a.m. Monday with a gunshot wound to the head in a room at the Whitehall Hotel, in the 100 block of East Delaware Place, police said.
"There were a slew of police on the seventh floor," said Florida guest Megan Cole as she left the hotel with her child in a stroller. "I hate to say it, but I hope it's someone she knew. I hate to think it was an intruder."
Police said Gardner's body was discovered in her seventh-floor hotel room by a cleaning crew who reported it to hotel management who called police. Her death has been ruled a homicide.
Gardner has a history of prostitution charges, including an arrest Aug. 8 in Chicago, authorities said. Police have yet to establish a motive in her death. They are investigating whether the killing is tied to prostitution.
Detectives asked officials at The Bristol, a condominium building next door to the hotel, for surveillance footage because the Whitehall Hotel did not have outdoor cameras, according Abel Angeles, a Doorman at Bristol.
The man arrested in the shooting has previous convictions for burglary and aggravated battery, according to the Tribune. No charges have been filed.
Representatives for Whitehall declined comment.
