A 21-year-old man pleaded guilty Friday to 11 charges, including second-degree murder, stemming from the robbery and assault that led to the 2010 death of an Eldorado High School teacher.
As part of a plea deal with Marcos Castrejon, prosecutors dropped 13 other felony counts. With the murder count, Castrejon pleaded guilty to five counts each of robbery and conspiracy.
He faces 10 to 130 years in prison. A sentencing date was set for April 27 before District Judge Jennifer Togliatti. Castrejon remained in the Clark County Detention Center.
Authorities say Castrejon and five others attacked Timothy VanDerbosch around 5 a.m. on Oct. 20, 2010, during a thrill-seeking robbery spree.
Before VanDerbosch, 50, could escape, authorities said, he was chased down and pummeled by the pack. They left him unconscious in the street.
Soon after, VanDerbosch was struck by a passing truck, near Washington Avenue and Betty Lane. He later died at University Medical Center.
The defendants were driving away and saw that VanDerbosch had been struck, Las Vegas police said.
The defendants thought the teacher had money based on how he was dressed, prosecutors said.
Three other defendants have agreed to plea deals in the case, including Daniel Carrillo, who pleaded guilty to second-degree murder and other charges last year. He was sentenced in October to 19 to 85 years in prison.
Saul Favela, 20, and David Rosas, 21, are awaiting trial. If convicted, Favela and Rosas could face the death penalty.
Authorities said the defendants began their spree about 1:30 a.m. by driving around the northeast valley seeking people to rob.
Investigators have described the group as a "party crew" motivated by the thrill of random violence against anyone they happened to meet.
There were nine victims before VanDerbosch: a man on his way to his first day at a cab company, a man and a woman walking home from a bus stop, a couple taking in the view of Las Vegas and a group of four people.
The cabdriver cooperated, giving up everything he had of value, but was still stabbed, police said.
Two other victims were pistol-whipped and suffered substantial injuries.
Prosecutors have said the defendants have made full confessions.
