PASCO COUNTY, Fla. (WTXL) - Three men have been arrested in connection with the roadside murder believed to be brought on by feuding between rival motorcycle gangs. 

The incident happened on Thursday at 4:53 p.m.

The Pasco County Sheriff's Office says that the victim, 44-year-old Paul Anderson, was driving a pick up truck on the Suncoast Parkway when two men on a motorcycle approached the truck.

The men got off their motorcycles and tapped on the window of the truck to get the Anderson's attention. That's when they fired several shots, killing Anderson. 

A third vehicle was involved, deputies say, and made sure the motorcyclists made a clean escape. 

The Sheriff says the victim was the president of the Cross Bayou Chapter of the Outlaw motorcycle gang. All three murder suspects were part of a rival motorcycle gang called the 69’ers.

In less than 24 hours, Christopher Brian Cosimano (nickname 'Durty'), Michael Dominick Mencher (nickname 'Pumpkin'), and Allan Burt Guinto (nickname 'Big Bee') were arrested for their part in the murder. 

Cosimano has been identified as the shooter and is the president of the 69’ers. Deputies say Mencher was the second motorcycle rider and say Guinto was driving the scout vehicle.

All three were charged with first degree premeditated murder. 

Deputies say that there has been feuding going back in forth between the two groups. 

"Will there be retaliation? I would hope and pray that there's not, but I believe there will be," said Pasco County Sheriff Chris Nocco. "We have information already there's people from motorcycle clubs coming into the state of Florida. So were just asking anybody out there, if you see something, say something."
