MARTINSBURG, WV - From Baltimore, we traveled on I-70 to I-81 and crossed into West Virginia by way of Berkeley County.
Timothy and Caitlyn Virts likely passed through the Martinsburg area if they headed to the southern part of the state.
Police say Timothy lived and worked there for a period of time.
"For him to get from Baltimore to the Southern part of West Virginia, he would probably come through the I-81 corridor," said TFC M.D. Gillmore, WV State Police.
The interstate has electronic signs, and State Police cruisers have technology to read license plates. TFC Gillmore was the first to give us a look at the actual car involved in the Amber Alert. It was caught on a plate reader after the alert was issued. The car has a Ravens decal on the left and Redskins on the right, along with a family of stick figures on the bottom.
"My eyes can only catch so much, but those cameras are going to catch every vehicle that passes us," said TFC Gillmore.
Police say there's no evidence to suggest the father and daughter are in West Virginia. However, the alert is traveling.
"The more you can get the news out the better," said Monroe.
