Cops: Neighbor killed Las Vegas mom and son, 8

LAS VEGAS -- Authorities released the identities Sunday of a Las Vegas mother and son shot dead by a neighbor who then turned the gun on himself.

Jennifer Bagley, 39, died from a gunshot wound and 8-year-old Lex Donoso died from more than one, the Clark County coroner's office said.

Jennifer Jacobs, a senior investigator with the office, said she did not yet have the shooter's identity confirmed.

A neighbor with a handgun fatally shot Bagley in her doorway Friday morning and snatched Donoso before a shot was heard and the bodies of the gunman and boy were found in the man's house two doors away, according to police.

Bagley's daughter escaped to another neighbor's home to summon police.

Patrol officers found a third child, a boy about 2 or 3 years old, unharmed in the house where the woman was killed.

Police Lt. Dan McGrath said officers tried unsuccessfully to contact the gunman before hearing at least one shot from his home.

SWAT team members entered the house and found the man dead of an apparent self-inflicted gunshot wound and a handgun near his body, McGrath said. Police say no officers fired shots, reports CBS affiliate KLAS.

Police responded to the Bagley home shortly after 7 a.m. and the barricade situation ended about an hour later, reports the station.

It wasn't immediately clear whether the gunman took Donoso alive to his home or shot him and carried his body after shooting Bagley.

Investigators were still trying to determine a motive.

"We're trying to put this all together right now," McGrath said. "It's unbelievable, it's tragic, it's gruesome to have a young child murdered."

Meanwhile, other residents on the street lined by stucco single-family homes with tile roofs just south of McCarran International Airport were trying to make sense of the shooting.

"We got to keep our heads up," Alberto Gonzalez told KTNV-TV. "Keep moving on just a little bit, and we just got a couple angels looking down."
