Mexico City ? A female wrestler suspected of killing at least 10 elderly women in Mexico City said she acted out of anger, apparently because her mother abandoned her and she was sexually abused, according to police and a videotaped confession broadcast Friday.

“I felt rage, anger, rancor,” 48-year-old Juana Barraza told two interrogators who could be heard but not seen on the video, played on the Televisa television network. Barraza said she killed the women because “they looked at me.”

“I never used my hands to strangle them,” she said, noting the killings were performed “with whatever I had in my hands … stockings, or scarves they had in their homes.”

The short-haired, robust Barraza – whose physique originally led police to question transvestites in the case – may have been acting out of anger for her own mother, around the same age as the victims.

Prosecutors said they have evidence implicating Barraza as the notorious “Mataviejitas,” or “Little Old Lady Killer.” They said she has confessed to four killings, and her fingerprints match those in a total of 10 cases.
