A St. Martinville man was arrested Sunday for what investigators have ruled a homicide.

St. Martin Parish Sheriff's Office spokeswoman Maj. Ginny Higgins reported 50-year-old Wilfred J. Viator is accused of killing his stepbrother 47 year-old Darrell J. Guilbeaux of New Iberia.

Higgins said deputies responded to a call at 11:30 a.m. from the Parks area regarding a suicidal subject who was requesting assistance.

When deputies arrived, they found Guilbeaux's body inside the home with  the person who made the 911 call.

Investigators arrested Viator Sunday afternoon following an investigation into the incident.

Viator was booked into the St. Martin Parish Correctional Center on one count of second-degree murder.

No bond has been set.
