Beverly Hills Man Kills Son, 3, and Himself, Police Say : Violence: Child was shot while seated in car parked at Ventura County turnout. Father’s body lay nearby; he and boy’s mother had argued, authorities say.

A 37-year-old Beverly Hills resident shot and killed his 3-year-old son in southern Ventura County and then committed suicide after an apparent fight with the boy’s mother, authorities said Saturday.

Authorities found Scott Toke Nyegaard’s body about 5 p.m. Friday at a turnout overlooking the Pacific Ocean. Nyegaard’s body lay near the luxury sedan in which his son, Ian Carlos Nyegaard, was shot in the head while strapped in his car seat.

The Beverly Hills Police Department said Nyegaard’s girlfriend, Michele Saadeh, 37, had filed a missing person’s report Friday morning after she awoke and discovered her boyfriend and their child were gone.

“It appears that they had an argument during the night,” said Lt. Jim Smith, a department spokesman. “We don’t know exactly what took place during the argument, what may have happened, or if [Nyegaard] had any types of behavioral problems.”

Investigators discovered a suicide note in the car, but did not release details. Smith said Saadeh told police that her boyfriend and son had disappeared sometime after 5:30 a.m. and that at first she thought Nyegaard had taken Ian to the doctor.

“She said the child had been sick during the night,” Smith said.

Ventura County Senior Sheriff’s Deputy Chuck Buttell said that shortly before 5 p.m. a motorist alerted Port Hueneme police to the car parked at Robyn’s Point, a turnout on Deer Creek Road off the Pacific Coast Highway about 2 1/2 miles north of the Los Angeles County line. According to Ventura County Senior Deputy Coroner Craig Stevens, the deaths occurred about 8 a.m. Friday. Stevens said Nyegaard used a 9-millimeter semiautomatic pistol.

Smith said Saadeh told police Nyegaard had been unemployed for several years but that he had recently taken a new job. “I am sure [the shooting] stemmed from something out of the argument,” Smith said.
