Maryland police announced Wednesday that they closed a 51-year-old cold case murder of a sheriff’s captain found shot to death lying face down in a pool of his own blood in a country club parking lot. 

Montgomery County Department of Police said they revisited the October 23, 1971, shooting of Montgomery County Special Deputy Sheriff Capt. James Tappen Hall last year on the 50th anniversary of the homicide, and investigators honed in on a man who had been living in New York for over 45 years under a changed name. 

When confronted by cold case detectives, Larry David Smith, also known as Larry David Becker, allegedly admitted to shooting and killing Hall more than five decades ago when he was around 20 years old. The now 71-year-old waived his extradition and is expected to return to Maryland by the end of the week.

To date, Hall’s case is the oldest cold case solved by the Montgomery County Department of Police.

On Saturday, October 23, 1971, at approximately 10:40 p.m., Montgomery County police officers were called to the Manor Country Club in the 14900 block of Carrolton Rd. in Rockville, Maryland, after witnesses reported a man lying face down in the southeast parking lot.

Officers arrived at the scene and located Hall suffering from a gunshot wound. He was transported to an area hospital, where he succumbed to his injuries three days later.

Investigators believe that Hall interrupted a residential burglary in progress.

In the nearly a year since Montgomery County police’s cold case unit revisited Hall’s murder, Det. K. Leggett and Cpl. L. Killen combed through case files, recordings and interviewed witnesses, the department said. Through their investigation, Leggett and Killen narrowed in on one person, Larry David Becker.

In 1973, Becker was interviewed by investigators but had not been labeled a suspect.

Detectives determined that around 1975, Becker began using the last name Smith and had been living in Little Falls, New York, for over 45 years.

Leggett and Killen interviewed Smith in New York on Sept. 1. During that interview, Smith allegedly admitted to shooting Hall, so detectives applied for and received an arrest warrant charging him with murder. Smith was then arrested in New York and awaits extradition.
