2 dead in Las Vegas Strip shooting; 1 arrested after online argument, police say

LAS VEGAS -- Two people were killed in a shooting on the Las Vegas Strip late on Sunday, police said, adding that it appeared to be a targeted killing that followed an online argument.

Manuel Ruiz, 41, turned himself in to police in Henderson, Nevada Monday morning, Las Vegas police said.

He was taken into custody, and charged with open murder with a deadly weapon, police said.

Police on patrol near the Bellagio Hotel & Casino heard gunshots at about 10:40 p.m., the Las Vegas Metro Police said. As officers arrived on the scene, they found two people with gunshot wounds, both of whom were later pronounced dead, Walsh said.

Walsh described the shooting as an isolated and targeted incident. He said it came after a victim and the suspect argued on social media, he said.

"The shooting did not occur inside a casino. Please avoid the area," the department had earlier said on social media.

Police said the shooting was on the 3600-block of South Las Vegas Boulevard. The department in a subsequent message said homicide police were responding to the area.
