A newlywed couple in Texas was killed in a car crash

after leaving the courthouse following their wedding ceremony Friday

. Their car collided with a pickup truck, killing them both,

CBS News affiliate KFDM reported.

Harley Morgan, 19, and Rhiannon Boudreaux, 20, were merging onto a highway in Orange,

Texas, when they collided with a pickup truck towing

a trailer carrying a tractor, the Orange Police Department said.

The accident occurred just minutes after the two exchanged vows.

The sister and mother of the groom were behind the couple’s car and witnessed the crash.

“They had just gotten married,” Morgan’s mother, Kennia, told KFDM.

“They haven’t even been married for five minutes.”

Morgan was driving a 2004 Chevrolet, which collided with a 2015 Ford F-250 pickup truck, police said.

The couple was exiting the private drive of Justice of the

Peace Joy Dubose-Simonton when the vehicles collided.
