Police say surveillance video shows an argument staring with an unknown male and Marc Conn, along with his longtime girlfriend Billie Jo Goldsworthy, inside the McDonald’s.

When Conn tried to pull his girlfriend away, the criminal complaint says two McDonald’s employees identified as Davis and Martin intervened and could be seen pushing and punching Goldsworthy, who police say appeared to be pushing back.

Police said Goldsworthy continued to argue with employees and customers outside. She was then pepper-sprayed by a woman now identified as Rosser. Police say Johnson then dragged Goldsworthy to the ground by her hair. While she was down, police say Lett struck her in the face.
