The 8 News NOW I-Team learned that suspended Metro Police Officer Kenneth Lopera is suing the Las Vegas Metropolitan Police Department.

According to Lopera, the department’s internal investigation is self-incriminating.

On Monday, Lopera was arraigned on two felony charges, including involuntary manslaughter in the chokehold death of Tashi Farmer also known as Tashii Brown. The incident occurred in May after Officer Lopera chased the unarmed man out of a Las Vegas Strip casino.

Lopera is accused of using excessive force against Farmer (Brown) while trying to subdue him.  According to Metro Police, Lopera used his taser seven times, along with an unauthorized chokehold while trying to restrain Farmer (Brown).

Metro said Farmer (Brown) who initially approached police to ask for help and then ran away from them, died at the scene.  The Clark County Coroner ruled his death a homicide, but the coroner also noted that Farmer was on meth and had an enlarged heart.

LVMPD says Lopera violated several departmental policies when he chased, used a stun gun and choked Brown.

The arraignment marked the first time Farmer’s mother faced the man accused in her son’s death.

“As any parent would feel, she’s devastated,” said Andre Lagomarsino, attorney.  “Initially, it was very tough for her, and she still has a lot of tough days.”

While other family members have already filed a wrongful death lawsuit, Lagomarsino says Farmer’s mother is expected to file as well, by the end of the year.

Lopera suit against the Metro Police Department states, “LVMPD disguises administrative investigations as criminal investigations.”

Sheriff Joe Lombardo told reporters Lopera never made a statement to the team investigating the in custody death, but union reps say he did provide an interview and cooperated.

“We’re confident that he’ll be exonerated of all charges in the end,” said Scott Nicholas, LVPPA. “Unfortunately, he has to go through this process right now, but we’ll be behind him.”

According to Lopera’s lawsuit, a use of force hearing is scheduled for Thursday as part of Metro’s internal investigation.  However, Lopera argues that he’ll have to testify and provide self-incriminating statements which would violate his rights.
