NIAGARA FALLS – A Dollar Tree store manager was able to identify a suspect accused of stealing another shopper’s backpack by using a store security video.

As a result, police said, Kari L. Weston, 42, of Cleveland Avenue, was charged with fourth-degree grand larceny and criminal possession of stolen property after officers found her at her home with the backpack and its contents just before 11 a.m. Wednesday.

About an hour before that, a 20-year-old woman said she came into the Dollar Tree on Portage Road and left her pink backpack on a cart in the front of the store. She said the backpack contained her textbooks and a laptop computer. When she returned about 10 minutes later, the backpack was gone, the woman told police.

Weston told police she watched the backpack unattended for a short while, then decided to take it and leave, according to a police report.
