ABERDEEN, Md. — A Harford County Sheriff's Office deputy is recovering after being injured in the line of duty Tuesday.
It all started around 11:25am by Calvary Road and Snake Lane in Churchville.
That's where Lieutenant Robert Burgess was driving an unmarked police vehicle.
At this time Burgess noticed a Penske truck driving erratically.
Burgess tried pulling the truck over, but the driver refused to stop.
While fleeing, the Penske driver struck a U.S. Mail truck and then a second vehicle just a few minutes later on E. Churchville Road.
The getaway driver kept going, reaching I-95, at which point Maryland State Police joined the pursuit.
From there the driver entered oncoming traffic on the southbound side of the interstate.
Burgess attempted to deploy stop sticks, for which the driver initially avoided, resulting in collisions with several other vehicles, including a tractor-trailer and Tesla.
As the driver continued to swerve in and out of traffic, he struck Burgess.
In a further attempt to flee, the driver crossed over to the northbound side of I-95, where another Harford County Sheriff's deputy rammed it off the road.
This caused the Penske truck to go over and down a hill, north of Maryland house.
The driver was able to bail out, launching a search that ended with a person being taken into custody near exit 77.
Sheriff Jeff Gahler said the unidentified person was taken to a hospital, and has so far been non-responsive, meaning investigators aren't yet positive whether or not he was behind the wheel of the Penske.
Burgess was helicoptered to Shock Trauma for his injuries. Gahler said he was alert and conscious.
Inside the truck, deputies recovered containers of cooking oil that was stolen earlier in the day from an Applebee's in Aberdeen.
After several hours of lane closures, I-95 has reopened.
