CHICAGO (STMW) — A South Side man was sentenced to 20 years in prison Monday for abusing his then girlfriend’s baby son in 2009, abuse that led to the child’s death.

Tyrone Wilson pleaded guilty to murder on Monday and Judge Lawrence Flood sentenced him to 20 years in prison, Cook County State’s Attorney’s office spokesman Stephen Campbell said.

Wilson, of the 200 block of East 72nd Street, was was charged with the July 31, 2009, death of 1-year-old Nashawn Lewis.

The boy’s mother, Nashella Johnson, pleaded guilty to child endangerment in February 2010 in exchange for three years in prison, according to the state’s attorney’s office.

Johnson, the baby’s biological mother, took her son for a walk in his stroller in the 1600 block of West 79th Street and realized he was unresponsive, police said.

She took the boy to a nearby clinic, where employees called 911, police said. Paramedics took the boy to a hospital, where he was declared dead.

Prosecutors said Nashawn had third-degree burns, and scars on his buttocks and scalp. Wilson, Johnson’s boyfriend but not the boy’s father, told police he pulled Nashawn’s arm, causing him to fall and hit his head on a railing, according to court records.

Wilson also admitted pushing the boy, causing him to fall into a wall, according to prosecutors.
