Patrick and his dog, Lucky, were heading home to Reno when they both mysteriously vanished on April 13, 2011.
Cops in northern Nevada found Patrick's abandoned car off of I-80. He and Lucky were last seen alive near Wells, Nev., at 9 p.m., April 13.
Patrick Carnes' dog, Lucky, is a slightly overweight, 100-pound Akita/mixed-breed. Patrick's family tells cops the two were virtually inseparable.
Lucky, like most beloved dogs, loves playing with tennis balls.
This is a freeze-frame pulled from a Nevada Highway Patrolman's dashcam video showing a truck believe to be tied to the Patrick Carnes case.
Cops believe the distinct, albeit hard-to-decipher, logo in the upper left corner of this truck may help lead to the person responsible for Patrick Carnes' disappearance.
