It's an unthinkable tragedy... but neighbors say they're trying to learn from it, as they begin to heal.

On Saturday, a mother and her four sons died in a house fire, and now, neighbors are protecting their own homes in hopes a tragedy like this doesn't happen again.

Nothing is left of the mobile home in Ocala that caught on fire Saturday morning, killing Tabetha Belanger and her four sons... 6-year-old Hunter, 4-year-old Nicholas, 2-year-old Michael and 2-month-old Aron.

Officials' latest findings: The victims were alive when the fire started, but they aren't releasing the official cause of death yet.
It hasn't been released yet whether or not the 800-square-foot home had working smoke detectors.

Firefighters say... they will provide and install smoke alarms for citizens who can't afford them free of charge.
