A 61-year-old Aurora man has been convicted of several counts for throwing a rake at a passing Jeep last year, causing its driver to crash and leaving a 16-year-old girl riding inside the vehicle paralyzed, prosecutors say.

Kenneth Duane Schlager was found guilty of felony criminal mischief and three counts of misdemeanor reckless endangerment late Tuesday, according to the Adams County District Attorney’s Office.

Authorities say Schlager was raking leaving in his front yard on Nov. 1, 2015, when he yelled at the Jeep’s driver, 20-year-old Marcus Segura, to slow down.

Segura turned around and headed back toward Schlager to confront him, prosecutors say, and Schlager stood in the street holding the rake.

“The car swerved to avoid hitting Schlager who witnesses said swung his rake ‘like a baseball bat,’ letting it go before it struck and shattered the windshield,” the 17th Judicial District Attorney’s Office said in a Wednesday news release.

The rake broke the Jeep’s windshield, causing Segura to lose control, strike a parked car and roll over. The teen passenger, Segura’s sister, was paralyzed in the wreck.

After the violent crash, Schlager got another rake and continued with his chores, officials say.

Schalger told investigators after the crash that Segura’s Jeep was traveling about 70 mph when he threw the rake at the vehicle in a “defensive manner,” according to an arrest affidavit. A neighbor told police she had earlier seen Segura throw something at a passing motorcycle. No one was injured in that incident.

“He didn’t call 911 or offer to help. He had no regard for the violence and destruction he left around him,” Deputy District Attorney Rayna Gokli said in a statement.

The speed limit on the street was 25. Police said the Jeep was traveling at 36 miles per hour before the crash.

Schlager will be sentenced on Jan. 5.
