but only Amy was shot a second time with a different gun.

There'd been that spent .380 shell casing found in the yogurt shop drain, but back in 1991, Border Patrol doesn't know any of this.

The way state and federal authorities shared information was limited back then and less sophisticated.

Border Patrol confiscates Brashear's .380 and nothing at the time links Brashear's to this horrible Austin murder case.

Police get stopped in February in Georgia with another stolen car and burglary tools, police scanner, ends up getting charged federally for all this.

Once he's sentenced, his father petitioned to get the gun back and it was released to him.

Now we know why.

The gun was pretty important to him.

Breshears wanted it back because it linked him to a yogurt shop.

Robert Breshears is sentenced to five years in prison for stolen property and unlawfully possessing a firearm.

Brashears seems to have been on the move for decades.

After graduating high school, he joined the Navy in 1976.

He was soon discharged and by 1980 was living in New Orleans, Louisiana.

And the more authorities investigate this case, the crazier it gets.

Not only did Brashears appear to fake his own death, he was turning out to be one of the most elusive serial killers of the entire 1990s.

That's what's so scary about serial killers, is that you can't spot them.

It's not like TV.

They are among us.

They have families.

They have church groups.
