ZEPHYRHILLS, Fla. -- Armed with assault rifles and on the run, police across the country want to find three Pasco County siblings. Authorities say Ryan, Dylan, and Lee Grace Dougherty shot at a Zephyrhills Police officer as many as 20 times before robbing a bank in Valdosta, Georgia.
On Monday, the Pasco County Sheriff released dash cam video from Officer Kevin Widner's cruiser.
The video shows eight gunshots ringing out in the parking lot of a CVS Pharmacy last Tuesday morning. That was the 2nd time the Doughertys fired at Officer Widner after he tried to stop them for speeding through a 30 MPH zone.
Pasco County Sheriff Chris Nocco also says, at times, the Doughertys' vehicle attempted to "ambush" Officer Widner. "They were trying to hurt this officer if not kill him. So, we do know there were points where they slowed down in an attempt to kill this police officer."
At times, Officer Widner also told dispatchers the Doughertys were driving at "speeds over 100 miles per hour."
During the second blast of gunfire from the trio, one bullet blew out the police cruiser's tire. That let the Dougherty siblings get away and head straight to Valdosta, Georgia where they robbed a bank at gunpoint.
"They're very dangerous. They will shoot at us. They will shoot at our citizens," added Sheriff Nocco.
10 News also learned that before Ryan, Dylan, and Lee Grace began their crime spree, they had been living underground along a secluded road near Dade City. The Doughertys crafted a bunker from two semi trailers, complete with running water and wired for electricity.
Plus, Lee Grace Dougherty's Flickr page talks about her "huge crazy family." She also writes that she loves to "shoot guys" and "causing mayhem with [her] siblings."
It all raises some concerns for authorities about what the Doughertys are planning next.
On Monday, the siblings' mother, Barbara Bell, spoke out from her home in Jacksonville. She begged her children to give themselves up peacefully.
Police hope the Doughertys do surrender, but either way, authorities are hot on their trail. Reports have spotted them along I-75 from near Macon, Georgia to near Chattanooga, Tennesee.
Authorities urge anyone who spots the trio to stay away and call 911.
