Three suspects have been indicted in a bestiality case involving a suspect who is already accused of branding his initials onto a woman's private parts.

Mary Kanitz, 48, was arrested Sept. 18, a day after Christopher Jackson and Josephine Erikson. The Maricopa County Sheriff's Office announced Tuesday that all three have been indicted on bestiality charges stemming from a video allegedly made by Jackson in which Kanitz and Erikson appear to perform sex acts on the man's pet dog, a male German shepherd.

“If you saw the video, you’d be pretty sick,” Maricopa County Sheriff Joe Arpaio said in a statement released after the video was found. “We weren’t expecting this.”

An Arizona grand jury indicted the suspects of "knowingly engaging in sex acts with a dog," according to the Associated Press.

Officers found the video while searching Jackson's home in connection with a separate investigation, in which the 47-year-old small business owner is accused of drugging a woman and branding his initials, "CJ," onto her private parts.

Kanitz was taken into custody at the office of a Phoenix plastic surgeon, where she works, according to CBS affiliate KPHO.
