Museum Opens New Exhibit Detailing 1979 Lambertson Murder Case

On Tuesday, June 1, 2021, the Delaware State Police Museum revealed its new exbibit which detailed the events surrounding the Lambertson Murder Case and included the renown execution of the convicted murder Billy Bailey.

On May, 21, 1979, Bailey tragically shot and murdered Clara and Gilbert Lambertson inside of their home located just north of Dover. Bailey was a habitual offender who was facing possible life in prison for a recent check forgery conviction. On this date, Bailey committed an armed robbery of a local liquor store before traveling to the Lamberston’s residence. Shortly after the murders, Delaware State Police responded and canvassed the area for Bailey. Delaware State Police Aviation located Bailey fleeing on foot. As the helicopter was hovering close to the ground, a trooper pilot jumped from the aircraft and gave chase. Bailey fired a gunshot towards the pursuing trooper, but missed and was ultimately tackled and taken into custody.

Following a successful trial, Bailey was sentenced the death penalty. Bailey refused the option of dying by lethal injection and instead opted to be hanged. On January 25, 1996, Billy Bailey was the first to be hanged in Delaware since 1946 and only the third in the United States since 1965.
The Delaware State Police Museum located at 1425 North DuPont Highway, Dover, DE, 19901, is open and visitors are welcome. Our hours of operation are 10:00 AM - 4:00 PM, Tuesday - Saturday. We are closed on State and Federal Holidays. If you have questions, please call 302-739-7700.
