A 2-year-old boy and his father are dead after a suspected murder-suicide along the Appalachian Trail near Frederick County, and detectives were working into Friday night to pinpoint a motive.
Authorities identified the deceased as Frederick resident Sean M. Thomson, 34, and his son, Dawson Thomson. Their bodies, displaying “obvious trauma,” were found in rugged terrain near the Frederick-Washington county line in Boonsboro, according to a Maryland State Police news release, which classified the incident as an “apparent murder-suicide.” A knife was discovered at the scene.
Greg Shipley, a spokesman for MSP, said detectives were working to determine a motive Friday night. The mother and wife to the deceased described Sean Thomson as “despondent” of late, according to Shipley. The family had been living together, police said.
Sean Thomson reportedly picked up Dawson from his wife’s parents’ home near Boonsboro Thursday night and told the parents he was going hiking.
Around 10:30 p.m. Thursday, the concerned mother and wife contacted MSP after seeing Sean Thomson’s car in the parking lot in the 11000 block of Baltimore National Pike in Boonsboro.
Authorities began what would be a several-hour search involving multiple divisions, including the Mobile Field Force, Special Operations Division, Natural Resources Police and personnel trained in tracking.
Two-year-old Dawson’s body was found shortly after 3 a.m. in a ravine off the Appalachian Trail, more than a mile north of where the car was located. Sean Thomson’s body was located less than an hour later. The proximity of the two bodies to one another was not immediately clear.
Maryland State Police Homicide Unit investigators and crime scene technicians spent Friday processing the scene of the ongoing investigation. Anyone with information about the apparent crime is urged to contact the Frederick Barrack at 301-600-4151.
