I-Team: Police visited Las Vegas shooters multiple times

CHICAGO (WLS) -- New details emerged Wednesday about Jerad and Amanda Miller, the Northern Indiana couple that went on a shooting spree in Las Vegas Sunday, killing two police officers and a Wal-Mart shopper.

The seeds of the Millers' discontent with police were planted when Lafayette police searched their residence for weapons and drugs. Police ended up charging Mr. Miller.

After the couple left Indiana in January, they were driving past the Hoover Dam when Jerad Miller was stopped by police and his suspended Indiana license was confiscated.

Soon after, investigators say Miller left an angry phone message at the Indiana Bureau of Motor Vehicles headquarters in Indianapolis. The threatening message, according to police, said that he was going to shoot up the DMV.

Wednesday, Las Vegas police said their homeland security agents paid the Millers a visit in February in the wake of the incident.

"The male subject claimed that he used different terminology than what the Indiana DMV had told us," said Kevin McMahill of the Clark County Sheriff's Department, "but ultimately at the end of the conversation those three seasoned detectives did not determine that there was the potential for an ongoing threat at that time. The interaction with these officers was described as normal."

After that police in Las Vegas had two additional encounters with the future cop killers, but didn't know until the incident on Sunday that their hatred of police ran so deep.

"Because an individual may, online, espouse ideology that is anti-government or anti-police doesn't make them translate into a murderer," said McMahill. "What happened to change these two people into murderers we don't know, and we are working diligently to find out."

Las Vegas metro police said the most recent discussion they had with the police was a week ago, but again they say there were no red flags of an impending attack. According investigators, at least one of the guns used in the spree was purchased in Indiana.

Store security video also shows that the Millers did not kill each other to end the spree as originally thought. Instead, police say they killed Jerad first and then Amanda almost immediately killed herself.
