BURLINGTON, NC - A grandfather's tip led to four arrests in a sizable human trafficking bust in Alamance County.

In a Thursday morning news conference, Sheriff Terry Johnson and Alamance Co. District Attorney Pat Nadolski said at least two women were found to have been trafficked. Johnson said the investigation started after a man reported concerns about his granddaughter.

Some of the crimes occurred at room 224 at the Econo Lodge in Burlington. Deputies determined William Reynolds, Briana Morrison, Joseph Daniel and Carla Jo Bailey were living in the room. Cocaine and drug paraphernalia were found inside the room. Reynolds and Morrison were arrested by a US Marshals Task Force Wednesday at the hotel.

'The problem is much worse than we initially thought,' said Johnson.

Daniel, of Mebane, had four outstanding warrants including Common Law Robbery and Assault Inflicting Serious Bodily Injury. Bailey, of Siler City, was charged with one count of Possession of Cocaine and one count of Drug Paraphernalia.

Authorities are still investigating how many women were involved.

Reynolds is being held on a $3 million bond for multiple charges. Reynolds was charged with 14 counts of human Trafficking, 14 counts of Sexual Servitude and 1 count of Promoting Prostitution. The DA said Reynolds has 'a significant criminal record' and will face life in prison if convicted.
