SANFORD, Fla. -

The State Fire Marshal's Office is investigating two suspicious fires that gutted abandoned homes over the weekend. The fires may be linked to six others that have been set in Sanford since the beginning of July.

Sanford police said both fires were set within hours of each other along Palmetto Avenue from Saturday evening to early Sunday morning.

"I saw the glow," said Angelica Korynas, who lives nearby. "It was orange and it was already engulfed six or seven feet high."

No suspicious activity was reported leading up to the fires, but Korynas said she heard rustling in the leaves outside her window before the fires sparked up.

"When I looked out the window and didn't see (anything). Heard it again. Looked out the window again and I just saw flames."

In early July, a total of six fires destroyed abandoned homes and a historic schoolhouse in the Sanford area. Four of those fires were located on or near Palmetto Avenue.

The state fire marshal, along with an area task force, has been formed to figure out if the fires are related and how to prevent further fires from happening.
