Wilmington Teen's Drunken Dirt Bike Crash the 'Proximate Cause' of Twin's Death: Complaint

A Wilmington teen’s drunken dirt bike crash was the “proximate cause” of his twin brother’s death, according to a criminal complaint filed in Will County court.

Casey Grskovic, 19, was charged with two counts of aggravated driving under the influence and his bond was set at $200,000 Tuesday afternoon. He was released from jail hours later on $20,000 bail.

Grskovic was riding a dirt bike east on Widows Road Friday night and was following behind a dirt bike ridden by his twin brother, Ross Grskovic, police said. Neither dirt bike was street legal, according to police, but both brothers were riding on the roadway.

Another man was following the twins on a Harley Davidson, police said. This man, a 20-year-old, reportedly told county deputies he saw Casey Grskovic’s dirt bike clip the back of his brother’s dirt bike.

The 20-year-old reportedly performed CPR on Ross Grskovic until paramedics arrived. A man who had been riding on the back of the Harley was too distraught to speak with deputies, police said.

Both brothers were taken to Presence St. Joseph Medical Center in Joliet. Ross Grskovic died there. Casey Grskovic was released from the hospital Monday and taken to the Will County jail.

While Casey Grskovic was allegedly intoxicated at the time of the accident, his brother may have been drunk as well. A post to Ross Grskovic’s Twitter account from shortly before the crash said, “Not sober.”

The results of toxicological testing will not be returned for at least another two weeks, according to Will County Coroner Patrick O’Neil’s office.

An autopsy conducted Saturday on Ross Grskovic showed he suffered cranial cerebral injuries.

In 1998, the twins shared the role of “Baby Tristan” in the David Schwimmer-directed romantic comedy Since You’ve Been Gone.
