Chicago man stabbed girlfriend 150 times, then called 911 saying ‘it’s a bad day’: prosecutors

CHICAGO — Prosecutors say a Chicago man stabbed his girlfriend up to 150 times, killing her as she visited his house with their two young children on Monday.

Judge Mary Marubio held David Cobb, 37, without bail during a bond hearing on Thursday.

The couple had an on-and-off relationship for about five years, but they were together again at the time of the murder, Assistant State’s Attorney Mike Pekara told Marubio, according to a written proffer provided by the Cook County state’s attorney’s office.

After 8:30 p.m. Monday, Chicago’s 911 center received several calls from Cobb’s phone number from a man who kept saying, “it’s a bad day ever.” But the man could not provide an address.

Police dispatchers eventually figured out the call was coming from the 2400 block of East 74th Place, and they sent Chicago police officers to check it out.

Cobb opened the door to his third-floor apartment when police knocked around 9 p.m. The proffer said he was sitting just inside the doorway, bleeding heavily from both hands. His feet and clothing were bloody, too.

Officers found the couple’s two children, both younger than three years old, nearby. They were not injured.

The police searched the apartment and found Cobb’s 46-year-old girlfriend dead on the kitchen floor, officials said. Nearby, officers found two halves of a broken pair of scissors and a knife apparently covered with blood.

EMS took Cobb to a hospital for severe injuries to his hands, prosecutors said.

Prosecutors said the medical examiner identified “upwards of 150 stab wounds” on the woman, most to her back. The injuries were “consistent with having been made by scissors,” according to the proffer.

It said Cobb told police that the couple argued in the kitchen “and then everything went black and he then remembers blood everywhere and [he] tried to clean up.”

Officials said Cobb was convicted of domestic battery in 2006 and aggravated domestic battery in 2007, but those cases did not involve the murder victim. He also has a forgery conviction from 2009 and a narcotics possession charge from 2011, according to the proffer.

He is due back in court on August 15.
