New details of the hit-and-run accident that killed a Baltimore bicyclist last summer on Maryland Avenue have emerged, with news that the family of John R. Yates has sued the alleged driver and his employer, Potts & Callahan Inc.

The lawyer for Potts & Callahan told The Daily Record there’s no evidence that one of the company’s trucks hit Yates and that police tests of blood and hair on the bottom of the Potts & Callahan truck came back “inconclusive.”

But Yates’ family contends, in the $5 million lawsuit filed yesterday in Baltimore City Circuit Court, that a video captured by a nearby security camera shows one of the company’s trucks turning right onto Lafayette Avenue and failing to signal, just before the collision.
