The mystery of a box found Sunday on an Alabama Gulf Coast beach has apparently been solved.

WPMI is reporting that Daphne police have been contacted by a family connected to a blue box found by a would-be fisher on the sand in May Day Park.

Police believed the find was a “bereavement box” — a small urn that police believed contained the ashes of a baby boy, along with handmade baby clothes, clay footprints and handprints and a hospital bracelet from a hospital in Memphis.

Pictures of the find made their way to social media. According to Daphne police Sgt. Jason Vannoy, the box was an attempted burial at sea of the remains of a stillborn child, which was carried back to shore by the bay waters.

Police will let the family make a determination on what to do with the items.

“We, of course, understand that it was a very emotional situation, and we’re gonna give them the room that they need to make their decision,” Vannoy said.
