KILN, Miss. — Hancock County Sheriff Ricky Adam says 21-year-old Kevin Boudreaux (BOO'-droh) is in custody after allegedly shooting and killing his sister, 20-year-old Janelle Boudreaux.
Adam says the shooting happened during a dispute in Kiln.
Relatives told WLOX TV (http://bit.ly/VORorB ) the dispute started after the suspect ran into his ex-girlfriend at the Pass Christian parade.
The suspect reportedly wanted to reconcile and asked the ex-girlfriend to come to the Kiln home.
When the ex-girlfriend arrived at the house, authorities say the two began arguing. That's when the family said Janelle Boudreaux stepped in to break up the argument and was shot by her brother.
It was unclear whether Kevin Boudreaux has an attorney.
