Mexico City ? One is a female wrestler who allegedly earned the trust of elderly women, then strangled them. The other is a former soldier accused of luring gay men from bars and killing them.

Mexico City police had two suspected serial killers in custody Thursday, saying they have solved the capital’s infamous “Little Old Lady Killer” case and have broken another string of murders.

Authorities said Juana Barraza, 48, was caught fleeing a house Wednesday where an 82-year-old woman had been strangled with a stethoscope. Prosecutors said they have evidence implicating Barraza as the notorious “Mataviejitas,” or “Little Old Lady Killer,” suspected in the slayings of at least 10 elderly women in the past two years.

Another suspect, Raul Osiel Marroquin, 29, was arrested Monday in the killings of four homosexual men in the capital, police said.

Both suspects confessed to killing at least some of the victims when they were paraded in front of the media, a tradition in Mexico where police and prosecutors have faced withering criticism for failing to investigate, let alone solve, most crimes.

Mexico City Atty. Gen. Bernardo Batiz said Thursday that they have enough evidence to pin at least 10 deaths on Barraza, a stocky former professional wrestler.

Barraza was arrested Wednesday night as she fled a house where Ana Maria Reyes had just been strangled. Neighbors called police.
