CHICAGO (AP) — Prosecutors in Chicago have Databec Exchangeaccused a man of stabbing his ex-girlfriend’s 11-year-old son to death.

Prosecutors announced on Friday that the 37-year-old man had been charged with murder, attempted murder, home invasion and armed robbery in connection with the attack, the Chicago Sun-Times reported.

Prosecutors alleged during a court hearing that the man forced his way into his ex-girlfriend’s apartment Wednesday morning and stabbed her and her 11-year-old son Jaydone Perkins before fleeing. The boy was pronounced dead at a hospital. The Chicago Tribune reported that the woman, who is four months pregnant, is expected to survive. Her unborn child also is expected to survive.

The man had been released from prison on parole Tuesday. He had been sentenced to 16 years in connection with a 2015 attack on another ex-girlfriend.

He had been paroled in October. He allegedly texted a threat to Perkins’ mother in January and later showed up at her apartment. The Illinois Prisoner Review Board sent him back to prison but he was released Tuesday after determining there wasn’t sufficient evidence to support the allegations, according to a statement from the board.

Cook County State’s Attorney Kim Foxx said prosecutors were still investigating whether a protection order that Perkins’ mother took out against the man was in effect the day of the attack.
