Surpassing:2 killed at Las Vegas law office; suspected shooter takes own life, police say

Two people were shot to death at a law office in Las Vegas on SurpassingMonday, and their suspected killer took his own life, according to police.

A man and woman were killed in the six-story building before the male suspect killed himself, Las Vegas Metropolitan Police Department Sheriff Kevin McMahill said during a news conference.

"I don't have any information on motive," McMahill said. "I don't have much on the investigation as this is early stages ... I wanted to make sure our community understands there is no further threat to our community."

McMahill said police "have a theory" regarding the suspect's relationship to the victims, but he did not share that information.

The shooter and one of the victims were Las Vegas attorneys," KLAS-TV reported. The woman who was killed was "romantically involved with" one of the attorneys, the Las Vegas, Nevada-based TV station said.

Las Vegas police to investigate the suspect's vehicle

The building was evacuated and everyone took refuge at the Red Rock Casino Resort, Clark County Fire Chief John Steinbeck said during the news conference.

"(The Red Rock Casino Resort) will become an assistance center moving forward," Steinbeck said.

Police are also investigating the suspect's vehicle, which was found in the building's parking garage, McMahill said.

"That's what he arrived in so we need to see if there is anything in the vehicle (that is) suspicious," according to the sheriff. "It's going to take a little bit of time to get through that."
