A Miami woman convicted of killing two motorcyclists on Interstate 95 in Indian River County has been sentenced to 18 1/2 years in prison.

A judge sentenced 26-year-old Dominique Brice on Wednesday. A jury found Brice guilty last month of vehicular manslaughter.

Authorities say Brice was speeding and weaving through traffic in February 2008 when she hit Fritz Doucet and Raul Ortiz. They were recently reunited high school friends going to Bike Week in Daytona Beach.

Brice's brother and two small children were in the car.

Another driver on the interstate, who testified at the trial, had actually called 911 to report an erratic driver just moments before the crash.

Brice said she was just changing lanes when another car forced her out of control.
