WATERTOWN, Conn. (AP) – Lifeguards at Sylvan Lake Park rescued a woman who allegedly tried to commit suicide by driving her car into the lake, police said.

The incident occurred Monday morning while the lifeguards were giving swimming lessons. They told police that they heard a racing engine and saw a big splash as a car drove off Frost Bridge Road into the water.

Meghan Misset, an 18-year-old lifeguard, swam 100 yards to the car with another lifeguard, shattered the driver’s window with a rock, pulled out the driver and brought her to safety.

“I did what I had to do,” Misset said a few hours later. “I wasn’t thinking of anything else besides getting that woman out of the water.”

Police said the driver, a 32-year-old woman from New London, was trying to kill herself when she drove a Ford Escort into the lake around 11:30 a.m. The car sank into about 12 feet of water shortly after the driver was pulled free.

“Once they got her out, that thing went down,” officer Michael Markiewicz said.

The woman was belligerent with emergency workers and had to be handcuffed at the scene, police said. She was taken to Waterbury Hospital, though she appeared uninjured.

There was no additional information immediately available about the driver.
