"It works!" a beaming police operator said after handling the first call on the new 911 emergency telephone system in Houma, La.

"I got the call and a boy was hollering, `302 Mike Street is on fire!'," operator Jerry Duplantis said Thursday. "I said, `That's my house.' "Duplantis' 11-year-old son placed the call Wednesday. Three minutes after getting the call, Bayou Cane Fire Department volunteers were extinguishing the blaze.

"My biggest concern was for my kids," Duplantis said.

An ambulance driver phoned to tell Duplantis that his sons, Corey and Casey, hadn't been harmed in the blaze that moderately damaged the rented home but heavily damaged its contents.

The cause of the fire remains under investigation.
