The man who was killed Saturday in Prince George’s County by an apparent hit-and-run driver was a former Marine who had served in Afghanistan, his mother said.

Eric D. Bridgett, 27, of Clinton was found early Saturday at Kirby Road and Marwood Drive in the Clinton area, police said. They said preliminary investigation suggested that he was struck while trying to cross Kirby. The vehicle that hit him did not stop, police said.

His mother, Claudia Bridgett, said he was headed to his in-laws’ home, where his wife, Brandi, and their three children were staying while the couple looked for a home of their own. She said he had finished work at a restaurant and then stopped by his mother’s home in Clinton before heading to his in-laws’ house about 1 a.m.

Bridgett had a car, his mother said, but he liked to stay in shape and “loved to walk,” she said. He had attended Surratsville High School and been active in the ROTC program there.

It was not long after high school, she said, that he joined the Marines.

“I just knew he was going into the service,” she said. “He loved ROTC.”

He served for almost six years, which included two tours in Afghanistan, she said.

He had been out of the service for just over a year, she said, and had held several jobs in his return to civilian life. He was “trying to find that niche,” she said.

Claudia Bridgett said she had adopted her son when he was 16, after he had come to live with her at age 4.

Eric Bridgett was the father of a 4-month-old baby and 3- and 5-year-olds.

“He loved his family and had lots of friends,” she said.

Police said they were seeking information from anyone who might have witnessed the incident. They urged anyone with information to call 301-731-4422.
