Louisiana Driver Arrested After Livingston Parish Crash Kills Two Ohio Residents and Leaves Three Others Injured on Interstate 12

LIVINGSTON PARISH, LA — A 24-year-old Amite City man was arrested after a multivehicle crash in Livingston Parish left two Ohio residents dead and injured three others, Louisiana State Police said. Daniel Dennison was booked Saturday on two counts of vehicular homicide and a driving-while-impaired charge, along with violations for no insurance, no seat belt and simple possession of marijuana.

The crash happened late Friday night on Interstate 12 near La. 43 and is still under investigation. State police said Dennison was driving a 2017 Chevrolet Cruze eastbound when the collision unfolded, setting off a chain reaction that sent one vehicle across the median and into westbound traffic.

State police say the crash began when the Chevrolet moved into the left lane

Investigators said the Chevrolet Cruze was traveling in the right lane of I-12 while a 2024 Mercedes Sprinter van was eastbound beside it in the left lane. For reasons still under investigation, state police said the Chevrolet moved directly into the Mercedes’ path.

Both vehicles then went into the median and struck cable barriers. The Chevrolet came to a stop there, but the Mercedes kept moving beyond the barrier and entered the westbound lanes of the interstate, where the crash became even more severe.

The sequence of events remains under investigation, and troopers have not said why the Chevrolet shifted lanes before impact. Toxicology samples were collected from all of the drivers and sent for analysis.

Mercedes overturned and was struck by westbound tractor-trailer

After crossing into the opposite lanes, the Mercedes overturned and went directly into the path of a 2018 Kenworth tractor-trailer traveling westbound, police said. The truck then struck the overturned van.

The occupants of the Mercedes, a 54-year-old woman and a 47-year-old man from Beavercreek, Ohio, were pronounced dead at the scene. State police said the woman was driving and was properly restrained, while the male passenger was not wearing a seat belt.

The crash scene involved several vehicles and left investigators working through the sequence of impacts on both sides of the interstate. Authorities have not released additional details about the victims beyond their ages and hometown.

Dennison and the tractor-trailer occupants were taken to hospital with minor injuries

Dennison was not restrained and suffered minor injuries, according to state police. He was taken to a hospital after the crash and later determined to be impaired during the investigation.

The Kenworth driver and a passenger also sustained minor injuries and were transported to a hospital. Police said all of the injuries in those cases were described as minor.

The arrest followed the investigation into the fatal crash. According to an arrest record, Dennison is being held without bond on the vehicular homicide charges.

Charges include vehicular homicide, impaired driving and marijuana possession

In addition to the two vehicular homicide counts and the impaired-driving charge, Dennison was booked on no insurance, no seat belt and simple possession of marijuana violations, state police said. He was arrested Saturday after the crash and booked into the Livingston Parish Detention Center.

The case remains active, and investigators are still reviewing evidence from the scene and toxicology testing. State police said the samples from all drivers were submitted for analysis as they continue to determine exactly how the collision developed.

Interstate 12 crash adds to grim toll from late-night roadway collisions

The fatal wreck shut down a stretch of Interstate 12 investigation work that involved multiple lanes and directions of travel. The crash also underscores how quickly a lane change and median crossing can turn a two-vehicle encounter into a deadly pileup involving traffic in both directions.

State police have not announced any further arrests or additional suspects. For now, the case centers on the actions of the Chevrolet driver, the path of the Mercedes after impact and the role impairment may have played in the late-night crash.
