The search for justice for the San Francisco Giants fan who was severely beaten outside Dodger Stadium on Opening Day was bolstered by the appearance in Los Angeles on Thursday of about 200 billboards showing police sketches of the suspects, according to a Santa Cruz (Calif.) Sentinel report.

Lamar Advertising Co. donated the billboards, which tout a $100,000 reward for information that contributes to the apprehension of Bryan Stow's attackers, according to the report.

"I think it's a great thing that this company's doing this," LAPD detective P.J. Morris told the Sentinel, adding that representatives for Lamar had reached out last week to police about the possibility of putting up the billboards.

"I think it will certainly generate more people calling. Anything out there that can generate interest in the public, the better."

Stow, a 42-year-old paramedic and father of two, was beaten in a parking lot by two men in Dodgers gear after the March 31 season opener. He remains hospitalized with a coma in Los Angeles.

Preparations are being made to transfer Stow to UC San Francisco Medical Center, assuming his condition remains stable.

"We've had a couple rough patches. We've been here so long it kind of caught up to us," Stow's younger sister, Bonnie Stow, told the San Jose Mercury News. "He's responding more, and today [Wednesday] he was responding really well. It's a little more upbeat now. We can get him closer to home."
