New York State Police have started day two of a search for a missing Riverside woman with dementia who went missing.

Leading a team of about 60 local volunteer firefighters and other emergency personnel today, state police are hoping a wider search on Sunday can find 82-year-old Jean Taber.

Ms. Taber was last seen walking her dog on Route 104 in Riverside near her home at Riverwoods mobile home park. According to her grandson Mark Norton, she was wearing a yellow t-shirt, black fleece vest and khakis when she was last seen. The last confirmed video footage of Ms. Taber was about 2:15 p.m. Thursday.

State Trooper Tammy Mickoliger said Sunday morning that no evidence had been found during Saturday’s search.

“Things are evolving as we speak,” she said.

Ms. Mickoliger said that an air search had been conducted yesterday and another would be done today. Bloodhounds were brought down yesterday to search the area, and while no water search is being conducted, Ms. Mickoliger said that the search would expand to a top-to-bottom canvas of Riverwoods and the Route 104 area today.

“They’re turning over everything,” she said.

Correction: An earlier version of this article stated that Ms. Taber was last seen on Tuesday.
