Two young men were sentenced Thursday to 15 years to life in prison for the death of a Downey man who was struck on the head and suffered a fatal heart attack during a 2016 home-invasion robbery.

Paul Darvis Misikei, 22, and Sakaopo Atanasio Folau, 21, pleaded guilty in October to second-degree murder for the Jan. 17, 2016, death of Jim Rudometkin.

Two other men—31-year-old Henry Willie Sao of Long Beach, and Michael Harrod, 28—pleaded no contest to first-degree home invasion robbery for their role in the crime and were previously sentenced to six years in prison.

The county coroner’s office concluded that the 59-year-old victim died of a heart attack brought on by a combination of a stressful event and blunt force trauma, hypertensive cardiovascular disease and atherosclerotic cardiovascular disease.

Rudometkin had been struck on the head and bound by a ligature, according to the coroner’s office.

Police were sent to the victim’s home in the 10300 block of Lesterford Avenue about 11:15 a.m. that day following a call from a neighbor, and were told that men were seen running from the area.

The officers gave chase and apprehended Misikei and Sao; Folau and Harrod were arrested later.

The investigation “points to the victim being specifically targeted by the suspects,” Downey police Lt. Alex Irizabal said shortly after the crime. “We do not believe this was a random crime.”

Neighbors said Rudometkin was a well-liked local Realtor who had lived alone since his father’s death.
