CHARLOTTE COUNTY, Fla. - A crash between two motorcycles left a Port Charlotte man dead, and his brother critically injured.

According to Florida Highway Patrol, Anthony Semprevivo, 31, and Robert Semprevivo, 33 were traveling south on Sea Mist Drive when the accident happened. Troopers say Anthony sped up to pass his brother when the two collided.

"One of them overturned onto the shoulder in some shrubbery. The other one turned over on the roadway. Both the drivers were ejected," says Lt. Conner Cardwell, an FHP spokesperson on scene.

Anthony was brought to Englewood Community Hospital where he later died. Robert was bayflighted to Bayfront Medical Center where he remained in critical condition Wednesday night.

"My jaw dropped. I couldn't believe it," says Sandra Fraley, a childhood friend of the two.

Fraley was one of several friends who came out to the street where the brothers wrecked. She says word quickly spread about the accident.

"For this to happen is hard -- for everybody who loved them. They were well-known," Fraley says.

According to the FHP crash report, Anthony and Robert Semprevivo were both speeding, and neither was wearing a helmet.

Witnesses in the neighborhood were shocked to see and hear how fast the motorcycles were going.

"They gunned it and went past my driveway doing, I have to say, a hundred miles an hour. They were so fast," says Sheryl Hollar, who lives down the street from the accident site.

While troopers are not releasing many more details, as the investigation is still underway, several witnesses tell WINK News there was a third motorcyclist involved who left the scene of the accident.

"The guy on the red bike took his bike out of the bushes and looked at my daughter and said, 'Well, I didn't get hurt, so I'm taking off!'" says David Celani, who lives near the crash site.

FHP is not confirming or denying the presence of a third biker. Charges are pending, as are the results of the alcohol tests, according to the crash report.
