A 26-year-old off-duty D.C. police officer was killed yesterday in Northeast Washington when the bicycle she was riding was struck by a city-owned trash truck, according to police.

Police have identified the victim as Katheline Marino, who was assigned to the 5th District where she was the station clerk.

Marino joined the police department 4 1/2 years ago.

Marino was struck on Maryland Avenue near F Street NE about 1 p.m. and died about a half hour later at D.C. General Hospital, according to police.

"Both the truck driver and Marino were traveling southbound on Maryland Avenue when the truck overtook Marino and passed her," said Officer Bernice Young, a police spokeswoman.

"Marino was traveling in the right hand lane. The truck then made a right turn on to F Street, striking Marino and throwing her under the wheels of the truck," Young said. Young identified the driver of the Department of Public Works truck as Floyd J. Wilson, 51, of 56 P St. NW. Wilson has been charged with failure to give full time and attention to his driving and violation of the restrictions on his permit, Young said. She was unable to say what restrictions were violated.

Marino was the daughter of Richard Marino, a retired city police officer, and stepdaughter of Genevieve Marino, a District officer assigned to the communications division, according to police sources.

Capt. Bernard Dryden of the Fifth District said that Marino had worked the midnight shift for the past two years as a station clerk at the district headquarters, located on Bladensburg Road near New York Avenue NE.

"She was very conscientious about her work," Dryden said.

"She had to be good to stay in that job, which includes dealing with the public, answering the phone, releasing prisoners and handling a lot of paper work," he added.

Dryden said that Marino was quiet and kept to herself. He said she was single and lived alone near the 5th District building.
