The Alabama Law Enforcement Agency is investigating the death of a driver whose vehicle crashed into the Intra Coastal Waterway after a police chase.

Orange Beach police said the incident happened Friday near Cumberland Farms, 23679 Canal Rd., after authorities responded to a report of a vehicle striking a pedestrian.

A witness at the scene identified a vehicle believed to have been involved.

Police say the vehicle fled west on Canal Road and the chase reached an excessive speed.

The pursuing officer remained engaged at a safe distance, police said, but the suspect vehicle was unable to negotiate the 90 degree turn at Tacky Jacks in Gulf Shores and crashed, coming to rest submerged in the Intra Coastal Waterway.

Officers located the vehicle’s headlights underwater but could not save the life of the driver, whose name has not been released.
