A 23-year-old woman pleaded innocent Thursday to 49 counts of molesting three 11- and 12-year-old girls.
Lori Bartz of El Cajon was ordered held on $405,000 bail in Las Colinas County Jail by San Diego Municipal Judge Charles Hayes.
Deputy Dist. Atty. Mary Avery told Hayes that Bartz simulated the voice of the devil to frighten one 11-year-old victim and that Bartz was once institutionalized in a mental hospital.
"She has threatened to kill the parents of one victim," Avery said.
The prosecutor said that she met the girls at the swimming pool of her apartment complex and that some of the sex acts were committed on the grounds of a school and behind a roller skating rink. Nude photographs were taken of one girl, Avery said.
