Breaking News Update:  The city watch for Uylanda and Nickolas Holliman has been canceled in Memphis.  Just moments ago, Memphis Police canceled that alert.  They're not saying why, or where the mother and son are.  The Cordova mom and son vanished on Friday night. 

According to family members, a 37-year-old Cordova mother and her 2-year-old toddler son who were last seen in the community on Friday, were spotted on surveillance video Monday afternoon at a Kroger grocery store in Millington.

A little over four hours after Uylanda Holliman and her son Nickolas were spotted in surveillance footage, Memphis police called off a city watch for the mother and son. The city watch was issued shortly after 4 a.m. Monday.

It is unclear why the city watch was called off and police are not saying where the mother and son were found.

According to police, the mother and toddler were last seen leaving her house on Valley Glen Drive around 9 p.m. on Oct. 5.

She was last seen in her 2010 black Chevrolet AVeo, with a Tennessee license tag number 171YSL.

The car has onStar tracking device but the subscription has not been renewed, sister Tiffany Dean told FOX13 News. Representatives from onStar said they have no way to track the car.

Dean added her sister's cell phone and credit cards have not been used since Friday.

The mother is 5-foot-1 and weighs 167 pounds, has black hair, brown eyes and was last seen wearing a pink t-shirt under a blue sweatshirt and jeans.

Her son Nicholas also has black hair and brown eyes. The toddler is 3-foot tall, weighs 35 pounds, and was wearing a blue jacket with yellow stripes, police said.

Holliman also has a 15-year-old daughter but the teen was at her father's house on Friday, Dean also said.

Family members said the teen received her mother's cell phone shortly before going over to her father's house Friday evening.

Police did not issue an Amber Alert, only a city watch. The watch was canceled at around 9 p.m. Monday.

The cause of the mother's and son's disappearance remains under investigation.
