Family lawyer alleges Vegas officer misconduct in fatal case

LAS VEGAS -- Relatives of an unarmed man who died after a struggle with a police officer outside a Las Vegas casino want the officer fired and brought up on criminal charges for repeatedly using a stun gun and then placing the man in an unauthorized chokehold, a lawyer for the family said Thursday.

Las Vegas police also should stop using stun guns and training officers to use a neck restraint intended to cut off the flow of blood to the brain, lawyer Andre Lagomarsino said.

"This was a fatal cocktail of misconduct," Lagomarsino said a day after a top Las Vegas police official showed body-camera video of officer Kenneth Lopera using his stun gun seven times on Tashii S. Brown.

The officer also punched Brown several times and held him in a mixed martial-arts chokehold for more than a minute after a foot chase through The Venetian casino.

Lopera called the arm-around-the-neck maneuver a "rear naked choke," Clark County undersheriff Kevin McMahill said. It is not authorized by Las Vegas police.

McMahill said the hold differs from a department-taught technique called "lateral vascular neck restraint" or a carotid-artery hold proponents say does not impede breathing but instead restricts blood flow to the brain and causes loss of consciousness.

That method, which McMahill said can render a person unconscious within 10 seconds, is banned for use by police in many other cities, including New York, where the death of Eric Garner on a Staten Island sidewalk in July 2014 sparked a national debate about police brutality.

Records show Las Vegas police officers used the neck restraint 632 times over a 10-year span, including 51 times last year. That's about once a week.

In Los Angeles, by comparison, the carotid hold is considered lethal force, to be used only in life-and-death situations. Police there reported using it seven times in the last five years, including twice in 2016.

It could take several weeks to receive full test results and determine what caused Brown's death early Sunday, the Clark County coroner said.

Brown appeared to be sweating and agitated when he approached Lopera and a partner in a casino coffee shop. He said someone was chasing him and ran outside to a driveway, McMahill said.

The family lawyer said Brown usually took prescription medication for depression, but he did not know whether Brown had taken it Saturday night. Brown's mother said he was home when she went to bed. She noticed him missing Sunday morning.

In the casino driveway at 1 a.m., Lopera thought Brown was trying to carjack a pickup truck with two people inside, McMahill said. The officer fired the stun gun in a series of staccato bursts.

The pickup driver later said he did not think Brown posed a threat, McMahill said.

Video shows Brown stiffen and fall backward onto the pavement with his arms raised. Lopera shouts at him to get on his stomach. Brown rolls to his side as the officer fires another jolt from the stun gun.

"I will!" Brown cries out, "Please! Please!"

Lopera, who is white, and Brown, who is black, then wrestle as the officer attempts to handcuff him. Lopera punches Brown's head and neck from behind as Venetian security guards join the effort and other police officers arrive.
