A St. Leonard man assaulted and attempted to rape his girlfriend as their relationship was ending and later crashed his pickup truck into the front of her house, state police said.

Charles T. Fleet, 45, is charged with first-degree assault, second-degree attempted rape, reckless endangerment and false imprisonment.

On the evening of July 27, Fleet picked up the 38-year-old woman, also of St. Leonard, at work, and the two of them drove to Armory Road Self Storage in Prince Frederick, discussing their breakup along the way, said Sgt. William McMeins of the Maryland State Police.

At the storage complex, Fleet "announced his intent to have sex with her against her will," McMeins said. "She was able to fight him off, and in the course of fighting him off he stuck her with [a hypodermic] needle."

The victim told police that Fleet held her down and injected her in the side of her left leg, in the mid-calf area, before she could flee.

The victim sought treatment at Calvert Memorial Hospital. She was later released.

McMeins said the contents of the needle are being analyzed.

That night, authorities in Calvert began looking for Fleet.

He did not turn up until the next day, when officers found him between 10 and 10:30 a.m. after he drove across the victim's yard and slammed his pickup truck into her house, damaging the front porch and cracking the foundation, McMeins said.

Police said the crash was intentional, but Fleet's mother, Dorothy Fleet, said it was an accident.

"He passed out behind the wheel and had his foot on the accelerator," she said. "He wasn't going more than eight miles per hour."

No one was inside the house at the time of the crash.

And inside the truck, Fleet was already injured.

"He had wounds on his wrists," McMeins said.

After being hospitalized, Fleet was transferred to the Calvert County Detention Center.

Dorothy Fleet said she had not been worried about her son before, but that a breakup could cause a "major crisis" for anyone.

"My son had a lot of problems, and he tried to take it out on himself, not anybody else," she said. "And this is the end result."
