William Patrick Conboy, Jr.

Private William Conboy was shot and killed during an undercover narcotics operation at a hotel at 8777 Georgia Avenue in Silver Spring.

He and another undercover officer had met the two suspects in a hotel lobby where they were patted down before being taken to the suspects' room on the 10th floor. Instead of the anticipated cocaine purchase, one of the suspects drew a handgun and shot Private Conboy in the back. Backup officers immediately entered the room and fatally shot one of the suspects.

Private Conboy's partner was also shot and wounded by the suspect.

Private Conboy was a U.S. Marine Corps veteran and had served with the Montgomery County Police Department for three years. He was survived by his wife and 2-year-old daughter.

I retired in April 2015 after 41 years on the job. 20 years in Patrol and 21 Years as a Detective. My grandfather Patrick Conboy was born in PA in 1870 and I know William and I were related. I came on the job on 4/16/74 a few short months after William was murdered. Rest in peace brother. I hopefully will be able to get to MD. and visit William's place of honor. My sympathy to his family.
