Lehigh County Coroner Scott Grim confirmed Monday that Michael Sikler was murdered over the weekend.
After performing an autopsy, Grim said the 34-year-old Sikler died from "multiple sharp and blunt force trauma." He ruled his death a homicide.
Lehigh County District Attorney Jim Martin would not reveal what kind of weapon was used to inflict those fatal injuries or whether that weapon has been recovered.
Martin also would not comment on whether the murder is believed to be drug-related. In the past, Sikler has been charged with drug-related offenses.
But, seeking to alleviate fears in the community, Martin did say the crime is believed to be a "victim specific" -- meaning Sikler was not randomly targeted.
Deputy Coroner Rick Pender pronounced Sikler dead at 3:59 p.m. Sunday at his home at 732 W. Ott St.
Grim said the victim was killed at that address after 5 a.m. Saturday, which was the last time anyone saw him alive. His body was discovered by family members at 3 p.m. Sunday, according to the district attorney.
No one had been charged with the crime as of Monday afternoon.
The coroner's office and Allentown police are conducting the investigation, with the assistance of the district attorney and the Lehigh County Homicide Task Force.
Martin said it is the 12th homicide in Lehigh County this year and the 17th in Lehigh County. He said those statistics are "slightly lower" than 2012.
