PD: Man who attacked 3, killed 1 may have been delusional

LAS VEGAS - Authorities say a 32-year-old man accused of killing one man and severely wounding another in random knife attacks in Las Vegas made statements suggesting he was delusional.

Police on Thursday released a new photo of Richi Briones, taken after he was arrested at a bus stop Wednesday evening following a nine-hour hunt for an attacker who wielded a large survival-style knife while chasing another man east of downtown.

The violence started at about 9:30 a.m. in the area of Lamb Boulevard and Bonanza Drive.  Briones tried to stab the first victim, who was able to run away, according to investigators.

At 9:35 a.m. police said Briones went into the Big 5 on Charleston Boulevard and Lamb Boulevard and attempted to buy a shotgun, but he was denied by the the store.

From the Big 5, Briones went to the alley of a nearby sushi restaurant at 10:19 a.m. and randomly stabbed another man.  Police said the third victim, a man, was attacked from behind while standing at an AM/PM convenience store counter.  This happened around 10:49 a.m.  Officers said the man died.

Business owners in the area are shaken up by what is believed to be a random act of violence.

"I heard that the guy came down the alley, he stabbed a guy, he stabbed a man; the man walked into the restaurant over here and asked for help, and he was bleeding," said Maggie Smith, local business owner.
On Thursday, surveillance video of Briones leaving one of the multiple crime scenes was also released to the media.  A minivan that matched the description of Briones' mini van was seen leaving an alleyway at a shopping center near Charleston and Lamb on April 19, around 10:11 a.m.

Police said around the same time dispatchers received a 911 call about a stabbing.

Smith, who owns a hair salon doors down from the restaurant, said she didn't know what was happening.

"That's why we were all concerned," Smith said.  "We're all watching out. The lady over here (she said as she pointed) watched them put the guy in the ambulance. She knew he was bleeding. She's the one who told me 'look, look.'"

Meanwhile, Polo Armendarez, arrived at his business located next to the sushi restaurant only to find it flooded with police.  Speaking to 8 News NOW in Spanish he said, "when we got here the girls from the restaurant were outside. It was chaotic, and they told us someone had been stabbed."

Police said the random attack was the suspect's third victim.

Hours later, police found him at a bus stop in front of the boulder station casino.

"That was scary yesterday," Smith said.  "Very scary."   

The surviving victim is in critical condition.  The Clark County Coroner still hasn't released the name of the AM/PM customer who was killed.
