GAINESVILLE, FLA. -- The stolen car driven by the latest primary suspect in the stabbing deaths of five college students here last August contained items that could have been helpful in break-ins, according to police records.

When the suspect was arrested Sept. 7 after an armed robbery at a store in Ocala, Fla., police found in the car two pairs of gloves, a black T-shirt and a denim bike bag containing a large screwdriver, Ocala police said. The only weapon recovered was a revolver, police said.

The suspect surfaced this week after sources said tests showed marked similarities between his DNA and samples collected during the investigation. Further tests are expected to be finished next week.

The suspect, a 36-year-old man, is jailed on bond in the armed robbery and has not been charged in connection with the Gainesville slayings, which occurred about a week before and 30 miles from where he was arrested.

Those playing a pivotal role in the massive state investigation have hesitated to claim a major breakthrough.

"We have an individual who's being focused on, but we can't make any comment on any progress in that investigation," said John Joyce, task force spokesman.
