Bodies Found at Turnout Identified as Father, Son : Slayings: The Beverly Hills man had driven off with the boy after an argument with the 3-year-old’s mother, police say. A suicide note is found in the car.

A 37-year-old man who shot and killed his 3-year-old son and then committed suicide was a Beverly Hills resident who had taken off with the boy after a fight with the child’s mother, authorities said Saturday.

Authorities found Scott Toke Nyegaard dead about 5 p.m. Friday at a turnout overlooking the Pacific Ocean in southern Ventura County. Nyegaard’s body lay near the gray Nissan 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, had filed a missing person’s report at 9:47 a.m. Friday after she awoke and discovered that her boyfriend and their child were gone.

“It appears that they had an argument during the night,” Lt. Jim Smith said. “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 about its contents. Smith said Saadeh, 37, told police that her boyfriend and son had disappeared after 5:30 a.m. and that at first she thought that 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 an injured man and small child at Robyn’s Point, a turnout on Deer Creek Road off 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 in the shooting.

Smith said Saadeh told police that Nyegaard recently had gotten a job after being unemployed for several years. Smith added that the missing person’s report showed no indication that Nyegaard had any police record or history of firearms use.

“I am sure [the shooting] stemmed from something out of the argument,” Smith said.

Both the Beverly Hills Police Department and the Ventura County Sheriff’s Department major crimes unit are investigating the murder-suicide, but Buttell said the case is essentially closed.

“It’s over,” Buttell said. “We’re satisfied. [Nyegaard] killed the baby, and then he killed himself.”
