Lenny Robinson, who made international headlines three years ago as the "Route 29 Batman," was struck by a car and killed Sunday night outside of Hagerstown, Maryland. He was 51.

A Baltimore businessman, Robinson owned a replica of the Batman '66 Batmobile and a customized black Lamborghini, and visited children's hospitals dressed as the Caped Crusader. He was propelled to fame in March 2012 after he was pulled over -- in full costume -- by police in Silver Spring, Maryland. The video of the traffic stop became an Internet sensation.

According to The Washington Post, Robinson was on his way back from a car show in West Virginia Sunday when he experienced engine trouble on Interstate 70. State police say he stopped “partially in the fast lane,” and was checking the engine when a Toyota Camry struck the Batmobile, which then struck and killed Robinson.

The accident is under investigation.
