Anthony Allen Shore (born June 25, 1962) is a serial killer/paedophile who is responsible for the slayings of one woman and four girls. He operated from 1987 to 2000, and was known as the "Tourniquet Killer" because of his use of a ligature with either a toothbrush or bamboo stick to tighten or loosen the ligature. The instrument was similar to a twitch, a tool used by farmers to control horses. Laurie Lee Tremblay Shore's first known victim was Laurie Tremblay, who was killed in September 1986. Shore had attempted to sexually assault her. She was strangled. Maria Carmen Del Estrada Maria Carmen Del Estrada, 21, was killed in April 1992. She had been sexually assaulted and strangled. She was a Mexican immigrant from the state of Guerrero who came to the United States to have a better life. She was a small, petite woman, standing at a height of 5 foot 1 inch and weighing 104 pounds. She worked as a nanny with her best friend, Rosa. On April 16, 1992, Carmen's half naked body was found in the back of a Dairy Queen. Selma Janske On October 19, 1993, Shore entered the home of a fourteen-year-old female, then bound and sexually assaulted her; however, he did not kill her, and instead fled the scene on foot. Diana Rebollar Diana Rebollar, 9, was killed in August 1994. She had been beaten, sexually assaulted and strangled. She lived in the Heights area of Houston, at the front of a small duplex. One day, she went to the neighborhood store to buy a bag of sugar. Employees of the store saw her leave the store safely, but she never returned home. She was found the next day on a loading dock behind a building. One lead for police was given by a neighbor who described a van that frequented the area. She was connected to the Carmen Del Estrada case by the killer's MO: a rope with a bamboo stick attached was found around her neck. Dana Sanchez Dana Sanchez, 16, was killed in July 1995. Shore offered her a ride in his van. He made advances to her, which she resisted; she was then strangled. Seven days later, an anonymous telephone call to a local news station, actually made by Shore, directed police to her body.
