LOS ANGELES -- Police investigating the brutal Opening Day beating of San Francisco Giants fan Bryan Stow at Dodger Stadium said Tuesday that they have shifted their focus to identifying the woman who helped the two assailants escape after the attack.

Detective PJ Morris, the lead investigator in the case, said that new information has led them to believe the woman was wearing an Andre Ethier jersey on the night of the attack. Witnesses have described her as a 5-foot-2 or 5-foot-3 Latina in her 20s with brown or dyed hair in a ponytail.

Morris is leading a group of 17 detectives investigating the case. The department has received more than 500 tips from the public but no arrests have been made nearly seven weeks after the brutal attack.

Meanwhile, the reward for information leading to the arrest and conviction of the two suspects is now $200,000 after the Dodgers added $100,000 to the total Tuesday.

"We're eating, sleeping and breathing this case," Morris said. "It is extremely important. The Stow family deserves this. Los Angeles and the Dodgers family deserves this. We can't let an act like this go unsolved."

Morris said that investigators have traveled as far north as San Francisco and as far south as San Diego to pursue leads.

"We've gone all over," he said. "There are no limits. It's more than citywide, it's statewide. This is very important.

"I'm not surprised it has gone [seven weeks]. When you're looking for a needle, you've got to go through all the straw. But we're working on a lot of good stuff, a lot of promising stuff."

Stow, a 42-year-old father of two from Santa Cruz, has been in a coma since the brutal attack. He has a fractured skull and damage to both frontal lobes of his brain.

But his condition has stabilized enough in recent days that doctors at County USC Medical Center, where he had been receiving treatment since the attack, felt it was safe to transfer him Monday to San Francisco General Hospital, closer to his home.

"Bryan was where he needed to be. He got great care at USC. They saved his life. But now it's just so nice to have him back, closer to home," Stow's cousin, John Stow, told ESPNLosAngeles.com by phone on Monday night.

In the wake of the attack, the Dodgers committed to fund an increased police presence at Dodger Stadium to help fans feel safer.
