LOCKPORT (AP) — A 34-year-old Houma man has been named a suspect in the weekend stabbing deaths of a woman and her two young daughters, who were inside an apartment that was then set ablaze.

Lafourche Parish Sheriff Craig Webre says David Brown invoked his right to counsel when deputies began to question him about the triple homicides. Brown was booked with unauthorized entry into an inhabited dwelling and simple battery stemming from a separate incident the night of the murders. He is being held on $110,000 bond and under an additional hold placed by the Louisiana Department of Probation and Parole.

Webre said Monday that the investigation continues into the early Sunday deaths of Jacqueline Gautreaux Nieves, 6-year-old Gabriella Nieves and 20-month-old Isabella Nieves, who were found dead in their home.
