RENO, Nev. — Fire officials are continuing to investigate the cause of a suspicious blaze that killed two people in a Reno apartment building last week but they say it doesn’t appear to have been arson.

Reno police identified the two victims Wednesday as 45-year-old Paul Therrien and 58-year-old Cathy Costodio.

The Washoe County medical examiner says an autopsy determined that smoke inhalation likely contributed to their deaths but the exact cause of death is pending toxicology results.

The Reno Fire Department is investigating whether a space heater or discarded cigarettes may have sparked the blaze that broke out last Thursday at the Stardust Apartments west of downtown.

Fire officials say there’s no obvious evidence of arson or any other crimes that may have played a role in the blaze of the deaths.
