Who Gets The Sniper Reward?

With two suspects in custody for the deadly sniper shootings, officials will begin considering who will get the $500,000 reward.

"We're just celebrating the information that we were able to release (Thursday) and we'll begin to deal with that tomorrow," Montgomery County Police spokeswoman Lucille Baur said.

The fund, which started at $50,000 before growing tenfold, was offered for information leading to "the arrest and indictment" of those responsible for the attacks. County officials have yet to work out whether the reward could be shared by more than one individual offering vital information.

"I'm sure that that will be on the minds of many people who have called in tips who are wondering if it applies to them," Baur said. She said she expected county officials will work out details soon.

Maj. Greg Shipley, a spokesman for the Maryland State Police, said investigators know the identity of the person who called 911 and reported the blue Chevrolet Caprice in which John Allen Muhammad, 41, and John Lee Malvo, 17, were sleeping at a Maryland rest stop.

"He was certainly a concerned citizen who had, not long before, heard a broadcast for the lookout and was alert and spotted that vehicle," Shipley said.

Shipley said the individual's name is being withheld because he is a witness in a criminal investigation. The man lives in a bordering state, but comes to Maryland regularly for work, he said.

Another man who called about the car at the truck stop did come forward.

"If I had the money - which I don't care whether I get the money or not - it would probably go back to the families of the victims, the families of the people whose lives were taken," truck driver Ron Lantz told CBS News Early Show anchor Julie Chen.

But Baur said Lantz was not the first caller.

In addition to callers who reported seeing the car, others could have contributed information vital to the case in other ways and might be eligible for a share of the reward, Baur noted.

Montana developer Tim Blixseth helped launch a nationwide effort to raise money for the reward, giving $50,000 of his own money to match the county's initial reward fund.

Shipley noted that no one has been indicted in the case yet, although investigators made clear Thursday they expect the men will be charged in the slayings.
