NASHVILLE, Tenn. -- There are still questions as to why police said two men specifcally came to Nashville to assault homeless people.

The two men ended up charged with murder in the death of a person living on the streets.

When Timothy Webber was booked in Nashville on Thursday evening, it was not the first time he's had a mug shot taken.

The Lebanon resident was arrested twice before he was charged with the murder in the death of Tara Cole.

Lebanon Police Chief Scott Bowen described Webber's prior actions as "violent behavior."

Nothing in Webber's criminal history indicates prior acts of violence toward the homeless.

While Josh Dotts, who police said is the accused accomplice in Cole's death, has no criminal history in Lebanon, Webber has been charged with domestic assault and resisting arrest in a case that many on Lebanon's police force said they remember to this day.

An officer said he awoke to find Webber and another man urinating on his patrol car.

Police said that action showed just how bold Webber can be.

Investigators in Nashville said it was Webber who rolled Cole into the river from the dock where she was sleeping .

They said Cole drowned as a result.

Police said the death likely would never have been solved if the men and the two friends with them that night hadn't turned on each other.

After video of the four was broadcast on local television, investigators said the two friends called police not wanting to be implicated in the crime.

Even Webber turned on Dotts, his accused accomplice, according to police.

They said Webber told them it was Dotts, not he, who rolled Cole into the water.

The only two who really know what happened that night are Webber and Dotts, who are both in jail.

One of the other two men, Corey Cothran, said he didn't know anything.

It is unclear what the other men know about what happened that night.

They are considered witnesses, and have not been charged.
