(WINFIELD TWP.) DuPage County sheriff’s officers are searching for the car of a 27-year-old man who was found unresponsive on the side of a west suburban road late Friday in what police have deemed a homicide.

Enrique Hernandez Jr. was discovered about 11 p.m. at the intersection of Highlake and DuPage avenues in unincorporated West Chicago, according to sheriff’s office spokeswoman Dawn Domrose.

Hernandez, a West Chicago resident, was taken to Central DuPage Hospital in Winfield, where he was pronounced dead. Police have declined to say how he was killed. The DuPage County coroner’s office could not immediately be reached for more details.

Police said Hernandez was a documented gang member who was targeted in an isolated attack. Investigators are trying to find his silver or gray 2007 Chevrolet Aveo with an Illinois license plate number of R614016.

Anyone with information should call the sheriff’s office at (630) 407-2400.
