Palm Springs police said Sonya Barbour, 32, and fiance Glenn Martin, 31, had their 9-month-old baby with them when they were arrested at 3:40 a.m. Thursday at a Walmart store in Palm Springs, the South Florida Sun-Sentinel reported Monday.
Investigators said Barbour and Martin were attempting to leave the store with $2,388 worth of baby formula concealed under a blanket in their shopping cart.
Both said they have pain-pill addictions, with Barbour spending about $90 per day on drugs and Martin spending up to $125 per day.
Martin told investigators he has been stealing baby formula for about six months and has netted about $90,000 from selling it, police said.
Barbour and Martin were both charged with fraud, shoplifting, organized dealing in stolen property and child neglect. Martin was held in lieu of $43,000 bond and Barbour's bond was set at $35,000.
Their baby was turned over to the Florida Department of Children and Families, police said.
