A 28-year-old Snellville mom was still in jail late Saturday after store employees found her with a needle in her arm on the bathroom floor of the Kroger on Scenic Highway in Snellville, police said.

Her 18-month-old son was crying nearby in a child safety seat when the woman was found in the store earlier this week.

Jessica C. Widner, who was charged with child cruelty, is the most recent apparent example in a growing heroin problem in the suburbs.

A recent CDC study found heroin caused more overdose deaths that any other drug and the number of heroin-related deaths in 2015 tripled that of 1999.
