Coral Eugene Watts has confessed to killing 22 people. Here is a summary of some of the cases:

Oct. 31, 1979: Jeanne Clyne, 35, was stabbed to death on a sidewalk in the exclusive Detroit suburb of Grosse Point Farms (searchas she walked home from a doctor's appointment. Police said Watts stabbed Clyne at least 10 times with a woodworking tool similar to a screwdriver.

Sept. 5, 1981: Linda Tilley, 22, was drowned in the swimming pool at her Austin apartment complex. Houston police Sgt. Tom Ladd said Watts had trailed another girl for several hours from Houston but lost track of her in Austin and then spotted Tilley. Ladd said Tilley's death had been ruled accidental until Watts confessed.

Sept. 12, 1981: Elizabeth Montgomery, 25, was stabbed once outside her Houston apartment while she walked her dog. Police said Montgomery apparently made it home before dying. Less than two miles away, Susan Wolf, 21, was stabbed in the arm and chest outside her Houston apartment as she carried groceries from her car. Her body was found outside her apartment.

Jan. 4, 1982: Phyllis Tamm, 27, was found hanging from a small tree near Houston's Rice University. Tamm's death was not ruled a homicide until Watts' confession. The medical examiner could not tell if her death was a freak accident.

Jan. 17, 1982: Architecture student Margaret Fossi, 25, was found dead in the trunk of her car, which was parked at Rice University (search). She had been reported missing a day earlier. Fossi died by asphyxia caused by a blow to the throat. Watts told police that he later spotted Julia Sanchez on a freeway as she tried to fix a flat tire. Watts slashed Sanchez's throat and left her for dead, but she survived.

Jan. 29, 1982: Watts followed Alice Martell, 19, to her Seabrook apartment where he stabbed her three times with an ice pick. She survived.

Jan. 30, 1982: Watts unsuccessfully tried to kill Galveston resident Patty Johnson by slashing her throat. Another man had been sentenced to life in prison for the attack until Watts took responsibility.

Feb. 7, 1982: Elena Semander, 20, was found dead in a Houston trash bin. Watts said he strangled her with her shirt, then threw away her body.

March 20, 1982: Emily LaQua, 14, was strangled on her way to her new job as a waitress in Brookshire. She had just moved from Seattle to live with her father in Texas and at first was thought to have run away. Her body was found five months later stuffed in a culvert. This is the only case for which Watts did not receive immunity.

March 27, 1982: Edith Ledet, 34, was stabbed to death in Galveston as she returned home from a graduation party. Her body was found in a walkway near some apartments. Ledet was to have graduated later that day from the University of Texas Medical Branch, where she had earned her degree after giving up an accounting career. Later that morning, Watts attacked Glenda Kirby, who lived several blocks away. Kirby escaped Watts' grip because his hands were bloody from killing Ledet, prosecutor Ira Jones said.

April 15, 1982: Yolanda Gracia, 21, was stabbed to death in her front lawn as she returned home. She was found clutching a bag that contained her work shoes.

April 16, 1982: Carrie Jefferson, 32, was strangled and then stabbed twice as she returned home from her job at Houston's downtown post office. Watts buried Jefferson's body along White Oak Bayou.

April 21, 1982: Suzanne Searles, 25, was grabbed as she returned home from a party. Watts told police that while he was strangling her, he couldn't tell if she was dead so he held her head in a flowerpot full of water. Watts buried Searles, who had moved to Houston from Des Moines, Iowa. Her grave was the first to which he led police following his confession in 1982.

May 23, 1982: Michelle Maday, 20, was returning home about 4 a.m. when Watts choked her to death outside her apartment. Watts told police he took Maday's body into the apartment and dumped it in the bathtub. Watts was arrested later as he attempted to kill Lori Lister and her roommate, Melinda Aguilar.
