The mother of three Florida siblings being sought by the FBI is urging them to surrender after authorities say they fired shots at a Florida police car and then robbed a bank in south Georgia.

Barbara Bell told The Associated Press on Friday that she loves her daughter and two sons and hopes they give up before someone gets hurt.

Authorities have been pursuing Ryan Edward Dougherty, Dylan Dougherty Stanley and Lee Grace Dougherty since Tuesday.

Sheriff Chris Nocco of Pasco County, Fla., says they're suspects in a high-speed chase in Florida in which at least 20 gunshots were fired at a police car. The officer wasn't hurt.

The FBI suspects the siblings later robbed a bank in Valdosta, Ga.

Nocco says he fears they are on a "violent mission."
