Two people were killed in separate Ascension Parish crashes between late Tuesday night and early Wednesday morning.

A teenager died after his vehicle ran off the road and struck a tree on the side of Interstate 10, according to State Police. The driver was identified as Mason Pusey, 17, of St. Amant.

He was traveling westbound on I-10 about 11 p.m. Tuesday when the crash occurred near the La. 641 exit, State Police said. The investigation is ongoing.

Several hours later, shortly before 5 a.m. Wednesday, a bicyclist died after being struck by a vehicle on La. 22 near Melancon Road in Sorrento.

Jessica White Gibbs, 27, was transported to the hospital but pronounced dead a short time later, according to the Ascension Parish Sheriff's Office. That case also remains under investigation.
