Luis Alfredo de la Rosa Rios, 29, Ernesto Cisneros, 22, and Jesse Contreras, 34, are alleged to be members of the F-13 gang, according to a statement from the US Department of Justice. Rio’s alleged girlfriend Hayley Marie Grisham, 18, has also been charged.
According to the complaint, Arroyos was house-hunting on Monday with his girlfriend when a black pickup truck got in. Rios and Cisneros aimed guns at the officer and his girlfriend and removed the items from both, including the chains from Arroyos’ neck.
The statement stated that an exchange of fire took place between Arroios and the two suspects, then the Arroyos collapsed and the two suspects fled. Los Angeles County deputies responded to the scene and transported the officer to the hospital, where he died.
The complaint said that the four defendants were in the car and were allegedly at the scene of the theft and shooting. They are accused of violent crimes for aiding extortion, which may result in the death penalty and a minimum sentence of life imprisonment in federal prison without the possibility of parole.
CNN has reached out to the Los Angeles County District Attorney’s Office in an effort to contact legal representation for the defendants and is awaiting a response.
On Tuesday, Los Angeles Police Chief Michael Moore said Arroyos, 27, “was starting a very promising career.” He worked in the department for three years and was assigned to the department of Wilshire.
“He found himself, after working a series of days on a patrol, to take a day off, and enjoy it with his girlfriend in search of a home, a place to live, a place to buy and invest in this city and its future,” Moore said.
Arroyos is survived by his mother and stepfather.
“He was the only child, he had a promising future, a bright future that was brutally robbed by a street robbery,” the leader said.
The US Attorney’s office said in a press release that the F-13 is a “large, multi-generational street gang that has previously been the subject of federal trials, including two major racketeering cases.”
