Man, Isaiah Moreno, pleads to murder in stabbing of Esteven Ruiz-Cisneros on RTD bus in Denver

DENVER - A 21-year-old man pleaded guilty Thursday to fatally stabbing a man on an RTD bus in Denver last year, authorities said Thursday.

Isaiah Moreno pleaded guilty to second-degree murder in the stabbing death of 39-year-old Esteven Ruiz-Cisneros, said Denver district attorney spokeswoman Lynn Kimbrough.

Moreno is scheduled to be sentenced May 2 in Denver District Court. He faces up to 40 years in prison. Moreno is being held without bond in the Denver Detention Center.

The stabbing happened on the afternoon of April 9, 2013 aboard a bus that was stopped at a transfer location at Colfax Avenue and Federal Boulevard near Sports Authority Field.

Arriving officers found Ruiz-Cisneros suffering from a stab wound to the neck. He was taken by ambulance to Denver Health Medical Center, where he was later pronounced dead.

According to an arrest affidavit, gang unit Detective Alan Breneman responded to the stabbing call and spotted Moreno running west behind a building at 3445 W. Conejos Ave.

Breneman caught the fleeing man and took him to the ground, police said.

As Breneman and two other officers restrained and handcuffed Moreno, the man shouted: "That motherf----- stabbed my brother," according to the affidavit. But Moreno didn't say anything more, police said.

An investigator reviewed surveillance video from the bus and said it shows Moreno and Ruiz-Cisneros get on the bus at the same location. The bus reaches a turn-around point at Federal Boulevard, where Moreno gets off, but the victim stays on the bus, the affidavit said.

The video then shows Moreno re-enter the bus, approach Ruiz-Cisneros and stab him in the neck. Moreno then runs from the bus, according to the affidavit.

Detective Troy Bisgard reviewed a surveillance video from a dance hall at 1630 Federal Blvd. that shows a man running from the RTD bus, jump over a fence, take off his coat and throw it in a Dumpster, the affidavit said. Bisgard searched the area near the fence and found a Colorado identification card and credit card with Moreno's name on them.

When a homicide detective tried to interview Moreno later at police headquarters, the man said he was under the influence of "meth and heroin" and did not know where he was or what was happening, the affidavit said.
