The Sacramento County Sheriff's Office said a missing 10-day-old infant and her mother, who officials say disappeared Wednesday "under concerning circumstances," were found safe.

Deputies say 10-day-old Riley Stella Ruth Hermosillo and her mother, 41-year-old Alexisse Marshall, both from Sacramento, were last seen around 1:30 p.m. in the area of Elk Grove Florin Road and Gerber Road in Elk Grove. A family member reported them missing at approximately 5 p.m. after returning home and discovering both were gone.

Because Riley is a newborn and there are specific concerns about Marshall's well-being, both were considered at-risk, investigators said. At this time, deputies emphasized there was nothing criminal known to be involved.
