North Edmonton fire damages two homes under construction

Investigators are working to determine what could have caused a fire that reduced two homes under construction in northeast Edmonton to rubble Monday morning.
Fire crews were called to the scene near 77 Street and Crystallina Nera Drive at 2:34 a.m. Monday where they found two homes fully engulfed with flames. 
Firefighters had the blaze under control just before 3 a.m. but not before both homes, still under construction, were completely burned down.
The fire was declared out at 7 a.m.
