BIRMINGHAM, Ala. (AP) - Investigators have determined that a fire which killed eight people at an Alabama marina earlier this year was an accident.

Scottsboro Fire Chief Gene Necklaus said in an email Wednesday that the blaze originated on one boat at Jackson County Park Marina.

He says it was an accident, but state investigators couldn't determine an exact cause.

The state fire marshal's office investigated the fire but has yet to respond to a request for a full report.

Fire erupted on a dock early on Jan. 27, and eight people died as wind blew the flames from one vessel to another.

The victims were identified as 38-year-old Amanda Foster, 54-year-old Yancy Ferrell Roper, 40-year-old Grace Annette Watson Miles and her five children. Her children are 19-year-old Christopher Zane Long, 16-year-old Bryli Anniston Long, 10-year-old Traydon Dominic Miles, 9-year-old Kesston Damien Miles and 7-year-old Dezli Nicole Miles.
