Firefighters say two men are dead after a two-alarm fire in four-plex in Metairie early Thursday morning.

According to the Jefferson Parish Fire Department, the fire happened around 2:58 a.m. in the 700 block of Orion Avenue, just one block off of Veterans Memorial Boulevard. Fire Chief Dave Tibbetts said firefighters found one of the units in the two-story fourplex "fully involved in fire."

Investigators say the body of a 82-year-old father and his 56-year-old son were found inside the apartment. The apartment did not have any working smoke alarms.

According to the New Orleans Advocate, the men were identified as Lisle House, and his son, Timothy House by parish coroner Gerry Cvitanovich.

A report by the Associated Press said Cvitanovich stated the men died from smoke inhalation.

Seven other people were inside the building at the time of the fire but were not injured.

The fire was classified as "under control" at 3:30 a.m. Thursday.

Fire investigators from JPFD, Jefferson Parish Sheriff's Office and the Louisiana State Fire Marshal's Office are trying to determine what caused the fire.
