The family of a young man who died in a car crash is suing the owner of a bar in Port Barrington, claiming that the servers got the driver of the car drunk before the accident that killed both men.

Robert Sloan Jr., 22, of Algonquin, was the passenger and Bradley Kass, 25, of Algonquin, was the driver when the car they were in struck a tree on May 2, police said.

Nancy and Robert Sloan Sr. filed the suit in June on behalf of their son. Before the crash, the suit alleged, the two men involved had been drinking at the Broken Oar, a bar on the Fox River. Bar workers caused Kass's intoxication by serving him alcohol, the suit alleged.

The two had been at the bar with other friends before leaving together, and both were intoxicated, said Matt Rundio, the attorney for the Sloans.

But attorneys for bar owner Michael Haber filed court documents denying the claims in the lawsuit and stating that Sloan Jr. "was guilty of complicity" because he "willfully caused the intoxication" of Kass, and encouraged his drinking.

McHenry County Sheriff's police reported that the two were in a 2005 Dodge Neon traveling south on Rawson Bridge Road early on May 2 when the car crossed the center line on a curve, went off the road and hit a tree near Cary, a little over a mile from the bar. Police responded around 2:30 a.m. and said alcohol might have been a contributing factor.

Sloan was an apprentice plumber, and Kass was employed by a landscaping and snow removal company, according to their obituaries.

At a hearing Tuesday in McHenry County Circuit Court, Rundio said, Judge Michael Caldwell ordered the bar to preserve evidence from that night, which might include video surveillance.
