A New Lenox man has been charged today in relation to a Labor Day weekend crash that left a 4-year-old girl dead.

McHenry County Sheriff Keith Nygren announced Monday the result of a five-month investigation regarding a traffic crash that occurred at 9:30 p.m. Sept. 2, 2012, at the Route 176 and Millstream Road intersection in unincorporated Seneca Township.

Leonardo R. Martinez, 43, 661 Edgewater Ct., New Lenox, was charged with:

• Aggravated driving under the influence
• Driving under the influence of drugs
• Driving Under the Combined Influence of Alcohol and Drugs
• Failure to stop at a stop sign

Martinez was driving a 2011 Infiniti QX56 and traveling southbound on Millstream Road when his car collided with a 2000 Jeep Grand Cherokee traveling westbound on Route 176, Nygren said.

Martinez failed to stop for the stop sign at the intersection and struck the Jeep, which was not required to stop at this intersection. Both vehicles exited the southwest corner of the intersection and crashed into a guard rail, where they came to rest.

A four year old female passenger from the Jeep died as a result of injuries sustained from this traffic crash, Nygren said.

As a result of the investigation a warrant of arrest was obtained for Martinez. He was arrested on Friday, March 1, with assistance from the McHenry County Sheriff’s Office Fugitive Apprehension Unit, without incident and transported to the Lake County Jail, Nygren said.

Bond for Martinez was set at $100,000. He is scheduled to appear in court March 20.

The incident was investigated by the McHenry County Sheriff’s Office Major Accident Investigations Unit.
