A woman who may have been driving under the influence of drugs and or alcohol crashed her car into a parked vehicle on the Garden State Parkway and killed her passenger Thursday afternoon, police said.

Sgt. Steve Jones, spokesman for the New Jersey State Police, said Autumn Steward, 29, of Wildwood, was traveling northbound at mile marker 25.2 in Upper Township at 2:35 p.m. when she crashed her sport utility vehicle into a tow truck on the road's shoulder.

The crash killed Henry Anholt, 42, of the Rio Grande section of Middle Township, who was sitting in the front passenger seat, Jones said.

Anholt was pronounced dead at the scene about 12 minutes after the accident.

The tow truck was responding to a previous minor accident at the location, Jones said.

Jones said police believe drugs and or alcohol may have been a factor in the crash. Police took a blood sample from Steward.

Steward was taken to AtlantiCare Regional Medical Center in Atlantic City for her injuries. She is listed in stable condition.

The crash closed traffic on the highway for a few hours, he said.
