Waterford — Before crashing his vehicle on Route 32 north Thursday, state Sen. Andrew Maynard, D-Stonington, was swerving between lanes and struck another vehicle, according to a man who said his wife's car was struck by the senator's vehicle.

As of late Friday afternoon, Maynard was reported to be under observation at a local hospital, and the other driver, who initially refused treatment, was seeking medical attention for neck and shoulder pain, according to her husband.

Pietro Scelfo said his wife, Laury Benjamin-Scelfo, had just visited her mother in New London and was on her way home to Uncasville on Route 32.

Scelfo said his wife looked into her rear-view mirror and saw that a vehicle was fast approaching and swerving between lanes.

He said she was driving in the righthand lane and attempted to go to the left lane to avoid the oncoming vehicle, but it clipped the right front quarter panel of her 2005 Chevrolet TrailBlazer.

Waterford police confirmed Friday that Maynard was involved in a two-car accident but said Friday evening the accident remains under investigation, and they would have no further report until next week.

On Thursday evening The Day reported that Maynard was involved in a one-car accident, based on information provided by police and State Senate Democratic Caucus spokesman Adam Joseph.

Police said initially the accident was reported as a car into a ditch, but they then discovered that Maynard's car had struck another car.

The accident occurred at 3:32 p.m. on Route 32 in the area of Scotch Cap Road.

Police said Maynard's vehicle traveled off the roadway and down a small embankment. The air bag in his vehicle deployed.

Joseph said by phone around 4:30 p.m. Friday that Maynard is under observation at an area hospital. He did not provide any further details.

The senator was initially taken to Lawrence + Memorial Hospital in New London. A spokesman for the hospital said Friday he could not respond to The Day's request for information about Maynard.

The Senate Democrats' spokesman told the media shortly after the crash that Maynard was involved in a single-car accident.

On Friday, however, he said that he had received his earlier information from numerous sources in the Waterford area who reported it as a single-car accident, although he did not disclose who they were.

Scelfo met his wife, the driver of the other car, at the scene. Police there told him that Maynard appeared to have a medical issue, perhaps a seizure.

"He was unconscious in the vehicle and had a cut on his forehead," Scelfo said. "That's all they told us. His car was resting on its right side on a tree."

Scelfo questioned whether the senator was fit to drive, since he suffered a traumatic brain injury in a July 2014 fall at his home in Stonington.

Joseph, the caucus spokesman, said Maynard had been cleared to drive.

Scelfo said his wife, who is 27, refused medical attention Thursday, but was going to get evaluated Friday since she now has neck and shoulder pain.

"The car was totaled," Scelfo said. "The (impact) broke off the right front suspension."

He said his wife managed to safely pull the car into the shoulder.

Maynard has declined, through spokesmen, all requests for interviews by The Day since his 2014 hospitalization.

In fliers sent out to constituents earlier this month, Maynard said while he was still working on his speech, "my heart, will and drive have allowed me to accomplish great things last year ..."

Maynard is the chairman of the Transportation Committee; the new session of the legislature begins Feb. 3.

"I don't think this will affect his ability to serve," Joseph said.
