Douglas Macarthur Kimball Jr, a 48-year-old White man, was found shot to death inside his home on the 1000 block of Cabin Ridge Road west of Felton, Delaware, on September 6, 2015. Neighbors and friends described him as quiet, hardworking and helpful; he worked for Sea Watch in Milford and enjoyed tinkering with engines, gardening, crabbing, attending auctions and hunting for old bottles. In the hours before his death he had been helping a friend with a project and failed to show up as expected, prompting the friend to check on him and call police.

Troopers arrived about 10:45 p.m. for a welfare check and discovered Kimball in the living room, slumped in front of the television with multiple gunshot wounds to his upper torso. The death was ruled a homicide after autopsy. Investigators treated the residence as a crime scene and interviewed more than 25 people, but those interviews did not identify a suspect. Police publicly reiterated in September 2018 that the murder remained unsolved and asked for information about visitors to his home or his movements that evening.

If anyone knew Douglas, saw visitors at his Cabin Ridge Road home on September 6, 2015, or has information about his final hours, please come forward.
