Items belonging to two Idaho children missing since September were found inside a storage unit rented by their mother after they disappeared, an Idaho newspaper reported.

The items, including bicycles, photos and clothing, were identified as belonging to Joshua JJ Vallow, 7, and his sister, Tylee Ryan, 17, according to a report this week in the East Idaho News.

Their mother Lori Vallow rented the storage unit in Rexburg in October, the outlet reported.

Vallow, who reportedly was obsessed with death and the afterlife, and her new husband, doomsday author Chad Daybell, have been in Hawaii for at least two months, authorities say. They reportedly are not cooperating in the search for the children and have been named by police as persons of interest.

Surveillance video obtained by the local news outlet shows that in the weeks after she rented the unit, Vallow visited it multiple times, sometimes with a man who helped move items into and out of it. The man appears to be her brother, Alex Cox, who mysteriously died in December, the paper reported.

In January, after Vallows credit card was declined, the storage company contacted police, East Idaho News reported.
