Police investigate murder of woman and her two children

Lockport, La.- Detectives are investigating the homicide of a Lockport mother and her two daughters who were discovered after authorities responded to a fire at their apartment on Elliott Drive Sunday morning.

Investigators have identified the woman as 30-year-old Jacqueline Gautreaux Nieves and her two children as 7-year-old Gabriella Nieves and 1-year-old Isabella Nieves.

Detectives say each of the victim's was found with at least one stab wound and detectives believe the fire had been intentionally set.

Authorities have detained 32-year-old Carlos Nieves Jr., Jacqueline's husband and the father of the two girls, has been detained as a person of interest and is currently being questioned in regard to this incident. Investigators have not yet determined if there was a single perpetrator or multiple subjects.

"It is a horrific crime any time children are involved, and it's even more devastating when it's a family," said Lafourche Parish Sheriff Craig Webre. "Then you have the attempt to cover up the crime with arson. Obviously, this is an extremely rare and unique case. We have all the resources of the Lockport Police Department and the Lafourche Parish Sheriff's Office involved in this investigation."

"This was certainly something that was difficult to wake up to this morning, and we are going to have to come together as a community while we grieve for the family," said Lockport Police Chief Warren Vedros. "It's been about 40 years since we've had a homicide in the Town of Lockport."

The victims' bodies have been taken to the Jefferson Parish Forensic Center for a full autopsy scheduled for Monday.
