Billy Capra

Biography
Billy Capra was first seen suffocating a woman on a bridge in Portland. It was revealed that before coming to Portland where he purchased Bramble Haus Bed and Breakfast, the Ziegevolk attacked and impregnated 17 women in three cities across three states; Des Moines, Iowa, Detroit, Michigan and Tuscon, Arizona.

He kept women prisoners in the basement on the property, where he locked them in cages and used a gas to ensure they remained sedated so they couldn't escape. In Portland he targeted Lisa at the Blue Moon Bar while he was attempting to lure her the to Bramble House. Hank broke into the bed and breakfast and located the women trapped within the basement and with Nick's help freed the women.

He initially escaped but he was later found with Lisa from Blue Moon Bar and after a confrontation with the beast, Nick and Hank chased the Ziegevolk through a park and was eventually hit by a car by accident although they debilitated him, while being tended to by a paramedic, he released his pheromone that attracted the medic.
