New court documents released this week reveal that a bone fragment was found when forensic investigators took apart a hacksaw found in a dumpster near Brian Walshe's mother's home.

Police also found Ana's COVID-19 vaccination card, her Volkswagen keys, clothing and  jewelry. 

Surveillance footage also reveals that Brian Walshe bought cleaning supplies around the time of his wife's disappearance. The images show Walshe wearing a face mask and pushing a shopping cart in a Home Depot. He purchased several things, including mops, brushes,  tarps,  Scotch Heavy duty tape, a Tyvek suit coverall, two splash-resistant goggles, and more. 

When the Walshe home was searched, many of those items were found. 

Walshe was also spotted at a Lowe's. That is where he allegedly bought $450 worth of tools, including a hacksaw that contained the bone fragment.
