DAYTONA BEACH, Fla. (AP) _ Four people have been arrested in the grisly slayings of six people whose bodies were found in a blood-spattered Florida house, officials said Sunday.

Brandon Haught, Volusia County sheriff's spokesman, disclosed the arrests but offered no details. More information was expected to be released at a morning news conference.

Remains of the four men and two women were found in different rooms of a three-bedroom home in Deltona, about 25 miles north of Orlando.

Authorities have not offered a motive or disclosed how the victims died, although the sheriff said the crime scene was ``very, very brutal.''

The bodies were discovered after one victim's co-worker at Burger King called a friend and asked the person to visit the home because the victim had not arrived for work, officials said.

The sheriff's office on Saturday identified the victims as Michelle Ann Nathan, 19; Anthony Vega, 34; Roberto ``Tito'' Gonzalez, 28, of New York; Francisco Ayo Roman, 30; and Jonathan Gleason, 18. Authorities had not yet positively identified the sixth victim by late Saturday.

The killing spree in the working-class, bedroom community of more than 70,000 people was the deadliest in Florida since 1990, when a man whose car was repossessed shot eight people to death at a Jacksonville loan office before turning the gun on himself.
