JAMUL, Calif. -
Authorities Monday released the name of a murder victim whose badly burned body was found last week in the trunk of a torched sedan in Jamul.
Firefighters found the remains of 20-year-old Dillon A. Davis about 4:30 a.m. Thursday, after putting out the car fire in the 16200 block of Skyline Truck Trail, sheriff's Lt. Glenn Giannantonio said.
The lieutenant declined to reveal the cause of Davis' death, though he confirmed that it "definitely" was a homicide.
Investigators have little information about the victim, whose last known place of residence was 4S Ranch in northern San Diego County, and scant leads on what prompted the killing, according to Giannantonio.
"Right now it's just speculation as to what the motive might be," he said.
No suspects have been identified in the case.
Among the few things detectives have learned about Davis is that he has family living on the East Coast, the lieutenant said.
Authorities asked anyone with information about the case to call San Diego County Crime Stoppers at (888) 580-8477. Tipsters may remain anonymous and could be eligible for a reward of up to $1,000.
Possible connection to 4S Ranch Death?
10News learned Davis lived directly across the hall from 20-year-old Marine Jason Trout in a 4S Ranch home.
Trout mysteriously died in August and the cause of his death remains undetermined, but homicide investigators don't believe foul play factored in his death.
Investigators believe the fact that the deceased men lived in the same home is a coincidence.
"There's no connection between the two," Giannantonio told 10News.
Neighbors tell a different story, as numerous sources told 10News the house was a hub for drug activity and had been raided for drugs a week after Trout was found dead inside -- something investigators remain tight-lipped on.
"Is this drug related?" asked 10News reporter Vanessa Van Hyfte.
Giannantonio replied, "We do not know the motive for the murder."
10News learned from the realtor that the home was sold a few days ago at a drastically reduced price. Sources told 10News Davis and Trout rented rooms in the house from the previous owner, who now lives in Connecticut.
Investigators said they are trying to learn more about Davis, and whoever may have wanted him dead and for what reason.
A post on a Facebook page -- possibly belonging to Davis' aunt in Maryland -- read:"We lost a special, bright, outgoing, happy young man, Dillon Davis. RIP We miss you and love you."
Another post read: "Gone too soon but never will be forgotten Dillon. Love you so much."
