Scott Deangelo, the primary suspect in a second-degree murder investigation involving the human remains found in a Pearl City apartment, has been arrested.

The Honolulu Police Department said officers arrested Deangelo at around 5:45 p.m. in Laie.

UPDATE 4:50 p.m.

Honolulu police say they are looking for an “armed and dangerous” suspect and have opened a murder investigation after a Pearl City apartment fire led to the discovery of human remains Monday night.

Scott Deangelo, 32, is wanted for suspicion of second-degree murder after being identified as a suspect in the case, police said this afternoon.

Deangelo, according to CrimeStoppers, reportedly fled the scene of the fire at the apartment building at 906 Lehua Ave., where a male victim was found dead and with “suspicious injuries.”

Deangelo reportedly climbed out of a window in the building and fled in a white SUV with a firearm, which has not been recovered.

Honolulu Police Department officials said the victim and Deangelo are acquaintances.

CrimeStoppers and HPD are asking for the public’s assistance in finding Deangelo, but warned that he should be considered “armed and dangerous.”

Lt. Deena Thoemmes of HPD’s homicide detail said Deangelo’s vehicle was found on Kamehameha Highway in front of a Hauula residence.

Deangelo does not have a criminal history in Hawaii, she said.

A preliminary report from the Honolulu Fire Department said the fire was intentionally set, according to HPD.

HPD didn’t disclose additional information about the case, citing the ongoing investigation. No additional information about the victim’s injuries or his relationship with Deangelo was provided.
