THIBODAUX, La. – Deputies are investigating what they believe is a murder-suicide after a mother and daughter were found shot to death Sunday morning.

Lafourche Parish Sheriff’s Office said the bodies of 26-year-old Nakesha Carrere and 5-year-old Abigail Creamer were found in the 900 block of Burma Road just before noon.

Detectives said they also discovered a detailed letter inside the home which they believe was written by Carrere.

“This is a tragic incident, and we extend our heartfelt sympathies to the family,” said Sheriff Craig Webre. “Investigators are still processing evidence, but we are confident in our determination of a murder-suicide.”
