Authorities aren't saying much, but CenterPoint Energy officials confirm they were called to an electrical contact incident in the 3600 block of Nutwood Lane at Roseville in northwest Harris County on Sunday afternoon.
Harris County Precinct 4 Constable's Office deputies tell us the victims are a three-year-old boy and a five-year-old girl.
Neighbor Laurie McNeill says she heard a loud boom.
"There was a big bang and our electricity went off for a second, and me and my husband both ran outside because our grandson was playing," she said.
Once outside, McNeill found her grandson OK, but she says the two children next door were not.
"We looked across the fence and we noticed that two little kids were down, so my husband jumped the fence to help," McNeill said. "The little girl wasn't breathing at first, but then they gave her CPR -- her dad did -- and got her to breathing again."
The neighbor says she watched in horror as the children's parents rushed to get help.
"The little girl was burned on most of her upper body and the little boy was burned on his side and hand," McNeill said. ""They brought them out front to wait for the ambulance. I was on the phone with 911."
Both victims were flown to Shriners Burns Hospital in Galveston in critical condition.
CenterPoint is investigating this incident, working to determine what happened and how.
