MCAT Crime Scene Investigation scene on Brockway St, Palatine.
On Monday December 10, 2018 the identities were released of two deceased people at a crime scene at an apartment just west of Brockway Street north of Richmond Street in Palatine. The driver of a vehicle — that struck a Palatine police officer and a civilian very early Sunday morning in darkness — was identified as Leslie Vaughan, age 51, of the block of 300 North Brockway Street. Leslie Vaughan was shot and killed by police about 1:53 a.m. after he struck the police officer with his Chevy sedan.
The Cook County medical examiner’s office reported that Leslie Vaughan died as a result of multiple gunshot wounds.
After the crash and shooting, Palatine police immediately discovered the body of Polly Vaughan, age 74, inside her son’s apartment. Polly Vaughan, a resident of Peoria, Arizona, was Leslie Vaughan’s mother.
The Cook County Medical Examiner’s Office reported that Polly Vaughan died as a result of multiple sharp force injuries.
Palatine police and firefighter/paramedics responded about 1:51 AM Sunday December 9, 2018 to a report of a person murdered in the block of 300 North Brockway Street, Palatine, IL. Police and firefighter/paramedics received the report that a person called 9-1-1 to report that someone was murdered at the scene, and additionally that the caller was no longer at the scene. Police reported to the public Sunday morning at about 7:22 a.m. that while the police officers assigned to the call were outside the apartment building talking with a resident, a car was driven toward them at high speed. Police said the car veered onto the grass toward two police officers and a civilian, and hit one of the police officers and a civilian before crashing into the apartment building.
Within minutes of the arrival of police, “shots fired by the police” was declared. The officer struck by the vehicle was able to discharge his firearm, striking the driver multiple times. According to Palatine Police Department, the offender’s vehicle came to rest against 308 North Brockway Street, a multi-residence building. The driver was pronounced dead at the scene. Police officers immediately began checking residential units and discovered Polly Vaughan in one of the apartments.
The civilian and the police officer struck by the vehicle were treated by Palatine Fire Department Paramedics and transported to an area hospital. Early in the investigation, police released information to the public that “the driver of the vehicle and the deceased female appeared to be related.” Police officers also released information that they were confident that there was no threat to the community connected to the incident.
The Cook County Major Case Assistance Team (MCAT) is conducting the investigation into the officer-involved shooting and is also assisting Palatine Police Investigators with the investigation into the death of the woman. Investigators were at the scene the entire day on Sunday.
