A Las Vegas man videotaped himself fatally shooting a homeless person and critically wounding a man walking his dog in separate "thrill killing" attacks, police said.
Noah Green, 21, was being held without bail Wednesday after being booked on suspicion of murder and attempted murder, Clark County jail records show.
He is suspected of killing Brent Michael Lloyd, 48 on a sidewalk about 3.5 miles west of the Strip, just before dawn July 13, police said.
Surveillance video in the neighborhood captured the sleeping homeless man's murder, which helped lead detectives to the suspect, who lived in a nearby apartment complex, Las Vegas police Lt. Ray Spencer said.
After investigators targeted Green for Lloyd's slaying, they also linked him to a July 15 shooting in a park a few blocks away. In that attack, a man was walking his dog when he was shot in the chest with no warning, authorities said.
The dog owner was critically wounded and has not been identified.
"My opinion is that it appears to be a thrill killing," Spencer told reporters Monday. "This person is a homeless person who is sleeping. There's no incident contact prior to. And same thing with the man who's out walking his dog after work."
Police found video of both shootings on Green's phone, according to Spencer.
"The fact he recorded it ... he's definitely keeping it for his own use, to personally view it in the future," Spencer said.
Police began staking out Green's apartment Thursday night before they arrested him after a brief foot chase late Friday, authorities said.
Green's Glock 9 mm handgun, the same kind of weapon used to kill Lloyd, and his cellphone were taken into evidence, police said.
"What we learned is that Mr. Green, the phone in his possession showed both the homeless person being murdered unprovoked and it also showed the unprovoked shooting of the man walking his dog," Spencer said. "The videos are absolutely disturbing."
Green appeared before a Clark County judge, via a closed-circuit camera, on Wednesday, and he was ordered back to court Aug. 12.
The suspect did not have to enter a plea, but Deputy Special Public Defender Alzora Jackson expressed concern about his client's ability to assist in his own defense, the Las Vegas Review-Journal reported.
“I have some concerns regarding his ability to be competent at this time," Jackson said.
