La Salle County authorities have identified an Oglesby man as the motorist killed in a March 31 rollover crash in Wallace Township.

Jakob A. Mancilla, 24, was the driver and sole occupant of an automobile involved in a rollover crash at North 31st and East 12th roads, the La Salle County Coroner’s Office said in a Thursday news release.

Coroner Rich Ploch said the automobile left the roadway and came to rest in an adjacent farm field. A forensic investigative autopsy was conducted on Wednesday and preliminary results indicate he died from injuries sustained in the crash.

Further forensic and toxicology testing is pending the outcome, Ploch said.

This incident is under further investigation by the La Salle County Coroner’s Office and Sheriff’s Office. The cause of the crash is still under investigation.
