Two people died in a crash that shut down the southbound lanes of the Maine Turnpike in Ogunquit on Thursday morning.

Maine State Police identified the victims as Brian Ellis, 55, of Kittery, and Linda Huelsman, 64, of Kennebunk.

State police responded to the crash around 6:05 a.m. to find that a tractor trailer being driven northbound by Xiaoying Ma, 35, of New York City, had crashed through the median guardrail and collided with two vehicles traveling southbound.

Ma had lost control of the tractor trailer, which is owned by EW Logistics of Hauppage, New York. He was brought to York Hospital with non-life-threatening injuries, state police said.

Huelsman was driving a Cadillac sedan and died at the scene. Ellis was driving a Mack box truck owned by EAN Holdings of Tulsa, Oklahoma. He was brought to Portsmouth Regional Hospital, where he later died.

It was snowing Thursday morning and the weather is believed to have been a factor in the crash, police said. The Maine Turnpike Authority had reduced the speed limit on the highway to 45 mph just after 3 a.m. Thursday. The York County District Attorney’s Office will review the investigation to determine if there will be any criminal charges.

The Maine Turnpike Authority sent out an alert just before 6:30 a.m. saying there was a crash at mile 15 between the Wells and York exits. All southbound lanes near Exit 14 in Wells were closed for hours, and reopened around noon on Thursday.

The vehicles were spread across all three lanes, but police were able to briefly open the center lane to let stopped traffic through.

The turnpike authority also reported a crash at mile 57 in Cumberland that caused delays.
