A 58-year-old executive from Pennsylvania was identified yesterday by police as the man who was shot and killed during a robbery after a wedding reception in Northeast Washington over the weekend.

George F. Longshore, who was in Washington for the wedding of a family friend, was shot once in the chest near 14th and Quincy streets NE shortly before 11 p.m. Saturday, police said. He and three other people had just left a wedding reception at St. Francis Hall at the Franciscan Monastery when they were approached by assailants who demanded money, police said.

The assailants pistol-whipped three of the people and shot Longshore after he apparently tossed cash at them, police said.

Longshore, a vice president of a nonprofit health care company, died at Washington Hospital Center. The other victims were treated for head and facial wounds.

D.C. police said yesterday that they had canvassed the area several times but had not generated any strong leads. "Everything remains wide open for us," said Lt. Robert Glover, adding that investigators were not even sure how many assailants were involved in the killing.

Detectives were examining recent reports of assaults and robberies in the area to see whether the killing might be linked to other crimes, Glover said.

They also were investigating whether the slaying was related to a nonfatal shooting that occurred about five hours later in the 1000 block of Newton Street NE, police said. Glover said detectives had found no evidence conclusively linking the crimes.

He urged anyone with information to call investigators at 202-727-9099. Police offer rewards of as much as $25,000 for information leading to the arrest and conviction of a suspect in a homicide.

Meanwhile, Longshore's family and co-workers were trying to come to grips with his death.

Longshore was vice president of organization effectiveness and human resources for Catholic Health East, a nonprofit organization that has 43,000 employees and runs several hospitals and other health care sites in 11 states.

"We are deeply saddened by the death of our colleague," said Bob Stanek, president and chief executive of Catholic Health East. "As both a friend and co-worker, George was a man of great faith, peace and compassion. He worked tirelessly on behalf of Catholic health care. He was dedicated to his profession and to the growth of others, both personally and professionally. We extend our prayers and heartfelt sympathy to his family."

Sal Foti, a vice president at Catholic Health East, said Longshore was known for his compassion and kindness. "Everybody is broken up," Foti said. "He was a tremendous individual."

Before joining Catholic Health East in 1999, Longshore was president and chief executive of Longshore & Simmons, a consulting firm that specialized in health care. He co-founded the business in 1979, according to a statement issued by Catholic Health East.

Longshore lived in Elkins Park, just north of Philadelphia, police said. A woman who answered the family's phone declined to comment yesterday.
