LOXLEY, Ala. (WKRG) — As the sun beat down Wednesday morning at Love’s Truck Stop, a customer noticed two toddlers, a boy and a girl, walking around the very busy parking lot.

“There’s RV’s, there are trailers, there’s construction equipment, boats going through that front parking lot constantly,” says Doug Phillips with Loxley Police. “They would never have seen a child that small run-up underneath one of them.”

The children were naked, alone and Phillips says there was something else. “The children were covered quite intensely with feces.” He says it was in their hair, on their faces and had been there for days.

Inside a van parked in the front parking lot of the truck stop, a Romanian couple identified as their parents, 20-year-old Alex Busuioc and 19-year-old Larisa Suca, were found asleep, “while these kids were walking loose in the parking lot,” says Phillips.

Battling through a language barrier, police believe the couple was returning to Tennessee from a beach vacation. They are now facing felony charges of torture and willful abuse of a child. “Luckily somebody saw them and was able to call us so we were able to get the kids the help they needed,” says Phillips. “It goes without saying it’s a sickening incident to see a child in that condition.”

Investigators believe the van had been parked at Love’s for at least a couple of hours. They are unsure how the children were able to get out of the van.
