A memorial service for the Posen firefighter killed in an apparent drag racing accident over the weekend will be Thursday, officials said.

The service for Zachary Orel is scheduled at 7 p.m. at Parkview Christian Church,  11100 Orland Parkway in Orland Park. Before the service, firefighters will pay their respects privately, according to a Posen Fire Department news release.

Orel, 25, of New Lenox, joined the department in June.

"Zach was an outstanding young man who enjoyed his work and was very excited to begin his career in the fire service. He loved helping others and always started his shift with a smile on his face," Fire Chief Kevin Szewczyk said in the news release. "He will be truly missed."

Also killed in the crash was Bart Lenz, 21, also of New Lenox. A memorial service for Lenz will be held at the Harry E. Anderson VFW Post, 323 Old Hickory Road, New Lenox from 6 to 10 p.m. Thursday, according to his father.

The crash happened about 2 a.m. Saturday at Moni Drive and South Center Avenue, near New Lenox, when one vehicle carrying Orel and Lenz and another vehicle carrying three others drove through a chain-link fence and hit the Enbridge pipeline.

The driver of the other vehicle, Michael Piersma, 21, and back-seat passenger William Monreal, 20, both of New Lenox, were taken to Loyola University Medical Center in Maywood for burns, officials said. Their conditions were not available.

The front-seat passenger, Patrick Hall, 22, of New Lenox, was treated for minor burns and released from Silver Cross Hospital in Joliet, Will County Sheriff's Office news officials said.

The Enbridge pipeline that was struck has been shut down and is expected to be fully operational by Thursday, a spokesman said.
