LAS VEGAS (KLAS) — Las Vegas Metro police arrested a man Monday after they said he shot and killed his roommate, the 8 News Now Investigators have learned.

Police arrested Jesus Mendoza-Zarate, 24, on one charge of open murder on Jan. 2, records showed.

Mendoza-Zarate and his roommate, Jesus Hernandez-Castro, who police said was in his 20s, were arguing before the shooting at a garage in a home near Las Vegas Boulevard and Pecos Road in the east valley, police said.

Mendoza-Zarate initially lied to investigators, saying Hernandez-Castro had died by suicide, police said. Police said Mendoza-Zarate waited an hour to call for help.

Judge Rebecca Saxe ordered Mendoza-Zarate held without bail in a hearing Tuesday morning. He was due to return to court Thursday.
