Delaware State Police Fallen Hero Trooper Ronald L. CareyRonald L. CareyRibbon
Trooper Ronald L. Carey, 29 years of age, and his partner, Trooper David C. Yarrington, 24, attempted to capture two hold-up suspects at the Concord Motel, U.S. Route 202, Johnson’s Corner, Pennsylvania, on January 5, 1972. The result of this valorous act ended in tragedy as both Carey and Yarrington were killed. This dual tragedy was perhaps best summarized by Ronald Carey’s mother, who said of her son, “I suppose if he had to go, this is the way he wanted to go, but I didn’t think it would be so soon.” Ronald Carey became a trooper because he wanted to be respected. To his classmates, at the State Police Academy, he was the perfect cop (and) the kind of guy you’d hope your son grows up to be. Lt. Raymond Deputy, assistant Director of Training, characterized Carey as “dedicated, solemn, and trustworthy… he didn’t talk much.” Trooper Carey leaves a wife, Elizabeth Lee, and three children, Lynne Elaine, Jeffrey Ronald, and John William to carry on without him. Ronald Carey was the “ideal husband, helping with the diapers, dishes, and feeding the children.” Trooper Carey was buried in Lawn Croft Cemetery, Boothwyn, Pennsylvania on January 10, 1972. One thousand, two hundred policemen joined the family and friends of Trooper Ronald L. Carey at his funeral service and burial. John Harrington, national president of the Fraternal Order of Police said it (Carey’s funeral) was the largest funeral ever in the nation. Pastor Randy H. Carroll, of the Marcus Hook Baptist Church, put the death in perspective, stating, “The best appreciation you can show for his sacrifice is to be the kind of an officer he was.” (Click here for the newspaper article)



Delaware State Police Fallen Hero Trooper David C. YarringtonDavid C. YarringtonRibbon
At 3:41 A.M. on January 6, 1972 the following message was broadcast over the State Police radio: “To all cars, Trooer Yarrington expired at 2:45 A.M. this morning.” Trooper Yarrington, 24, a fellow classmate of Trooper Ronald Carey, became the second policeman killed in the hold-ups of two Pennsylvania -- Delaware state line motels. Nationwide attention was focused on Delaware, January 8-9, 1972, as funeral rites were held for two officers. Trooper Yarrington and Carey are only the second and third troopers to die by gunshot since the force was formed in 1923. Governor Russell Peterson expressed sorrow over the deaths. “This is a tragic reminder of the dangerous and courageous job that’s being done every day by out Delaware State Police. On behalf of the people of Delaware, I extend my deepest sympathy…” Trooper Yarrington was, according to Lt. Raymond Deputy, the opposite of Trooper Carey. Yarrington was, to quote the Lieutenant, “a fun loving guy who got a big kick out of everything.” David Yarrington, as remembered by a public school classmate, was “…the toughest kid around until the 7th grade and then he suddenly calmed down.” He became active in the Assembly of God Church and spoke of becoming a minister. David Yarrington is survived by his wife, Janice M. and a son David Jr. Trooper Yarrington was laid to rest in burial ceremonies at Silverbrook Cemetery, Wilmington, Delaware.

Exhibit Detailing The 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 Federal Holidays. If you have questions, please call 302-739-7700.
