Two Alabama residents were charged after intentionally dumping as much as 500 gallons of oil throughout two counties, according to authorities.
After the May 20 spill, a slick, 33-mile trail now marks roads in Lawrence County and Morgan County, Alabama. Crews spent almost 70 hours cleaning up the spill with 37 tons of sand, News 19 reported.
After some residents provided police with surveillance footage of the incident, a man and a woman, both from Courtland, Alabama, were charged with criminal littering and criminal mischief and arrested on Monday, online records show. Other charges in other jurisdictions are possible, according to police.
The sheriff's office believes the oil was "purposely" spilled, Chief Deputy Brian Covington told News 19.
A blue GMC pickup truck the pair was driving pulled a utility trailer with a container "capable of holding upwards of 500 gallons," the sheriff's office said.
The truck “randomly” discarded oil on the roadways before the rest was dumped on a road in Decatur, according to the Lawrence County Sheriff’s Office.
Bond for the arrested couple was set at $2,500 each.
