The bodies of four men and two women were discovered about 6:30 a.m. in a three-bedroom house about 25 miles north of Orlando after a Burger King employee asked a friend to check on them, Volusia County Sheriff Ben Johnson said.

Investigators confirmed to Local 6 News that some of the victims may have once stayed at a home about 5 miles from the crime scene on Providence Boulevard.

Officials said the victims ranged in age from 18 to the mid-30s, and said police technicians would have to use fingerprints and dental records to confirm each identity. A dog was also found dead in the home.

By Friday evening, officials had tentatively identified one victim through tattoos, but did not release the name. Autopsies were planned for Saturday and Sunday.

"It's a lot of trauma, a lot of blood splatter, just a very, very brutal crime," Johnson said.

Local 6 spoke to the couple who own the house.

They said shortly after they left for Maine earlier this summer a group of young men apparently moved into their vacant house. The men did not have permission to be there.

The homeowners said two people were later arrested for the alleged break-in.

Local 6 News reported that the unwelcome visitors were first discovered by the homeowner's granddaughter who would stop by to clean the pool.

She lived at the house where Friday's murders took place, according to Local 6 News.
