Katherine Lisa Sainz, 56, was last seen leaving her Phoenix residence in the 85041 area on June 16, 2023. She is described as Hispanic, brown hair and brown eyes, 5 feet 3 inches and about 180 pounds. At the time she was reportedly wearing a brown long sweater or skirt and brown knee-high boots.

Investigators noted a possible travel to Casa Grande, Arizona, about an hour south of Phoenix, and that she may have been with one or more unknown individuals, but there is no public timeline of her movements or identified companions. Her case was entered into NamUs and Detective Daniel Nonnemacher of the Phoenix Police Department was assigned.
