A mother and her two children are dead following an apparent murder-suicide at their family home in Florida.

At around 8:30 p.m. local time on Thursday, Feb. 26, deputies went to a home in Lakewood Ranch to do a welfare check, the Manatee County Sheriff’s Office (MCSO) said in a news release. The homeowner, who was in South America at the time, requested the welfare check after struggling to contact his wife and children.

Deputies entered the property based on observations they made from outside, the news release said, and they found a 14-year-old boy and an 11-year-old girl dead in separate rooms, while their 44-year-old mother was also found deceased in another room.

“We really don’t know all that was in her frame of mind. But we are very confident all the parties that were involved in this are accounted for,” said Randy Warren of the MCSO, according to Fox 13.

“There was no one else who entered the home or left the scene. As tragic as this is, it is really unimaginable that two children were killed in their home by a parent, and then she proceeded to take her own life,” he added.

A preliminary investigation suggests there is no further threat to the community, the MCSO said.

Warren said the mother and children’s deaths were a “violent scene,” Fox 13 and WFLA News Channel 8 reported.

“We have no incidents at this address. What we have discovered [is] that the family moved here from out of state, from Missouri, about 3 years ago, and we have not been out here for any calls,” said Warren, per Fox 13.

“There’s really nothing there that would have indicated this would have happened,” he added.
