William Lewis Reece appeared in Galveston County District Court on Wednesday morning, when he admitted to killing 12-year-old Laura Kate Smither and 17-year-old Jessica Lee Cain.
Later on Wednesday, the 62-year-old appeared in a Brazoria County Court, where he pleaded guilty for the murder of 20-year-old Kelli Ann Cox.
Reece was given a maximum life in prison sentence for each offense.
His violent crime spree in Texas and Oklahoma happened across a five-month span in 1997, during which he killed four victims and kidnapped another. The crimes happened after he had already served time in Oklahoma prison for the rape of two women there.
It took nearly two decades before he was linked to the cold murder cases.
Below is a timeline of his victims' disappearances, murders, and the investigation that led to his convictions.
April 3, 1997: Laura Kate Smither abduction and search
On the morning April 3, 1997, Laura Kate Smither went out jogging in her Friendswood neighborhood. Then she failed to come home.
For more than two weeks, 6,000 volunteers searched over 800 square miles for the 12-year-old girl.
April 20, 1997: Laura Kate Smither's body found
On April 20, 1997, 17 days after Laura disappeared, her body was found in a water retention pond near Pasadena several miles from her home.
May 17, 1997: Sandra Sapaugh abduction and escape
In the early morning of May 17, 1997, Sandra Sapaugh stopped at a Webster store to call a friend. She observed a white pickup truck and its driver staring at her.
She went back to her van, and headed to a nearby restaurant where she was to meet a friend. Sandra heard a strange noise coming from her tire, but managed to pull into the parking lot of the restaurant.
Before she could get out of her van, the driver of the pickup truck appeared at her window, explaining that he noticed that she had a flat tire. Sandra got out of the van and saw that the tire was flat. The man offered to help. He opened the hood of his truck and asked Sandra to reach into his truck and hand him a rag from the passenger side of the truck. As she leaned into the truck, the man came up behind her, placed a knife to her neck, pushed her into the truck, and ordered her to stay down.
The man then drove to the parking lot of a Motel 6. He stopped the truck, reached into Sandra's shirt, and ordered her to remove her pants. She refused.
They left the motel parking lot and the man drove north on I-45. The man again ordered Sandra to remove her pants. She asked if she could take her shoes off first. He agreed, but to "hurry up."
Sandra bent down, opened the passenger door and prepared to jump from the moving vehicle. The man grabbed her shirt, but Sandra jumped out, hit the ground, and rolled. She began running toward oncoming traffic as she heard the man's truck stop and begin reversing.
A female driver pulled over when she saw Sandra in the road. Sandra pointed up the road to the pickup truck, which was now reversing toward the women. The female driver helped Sandra into her car and drove back to the restaurant to call police.
July 15, 1997: Kelli Ann Cox disappearance
On July 15, 1997, Kelli Ann Cox took a daytime tour of a Denton, Texas jail with her fellow University of North Texas classmates.
When she left and went to her car, the 20-year-old Criminology student discovered that she had locked her keys in her car, and the spare key would not unlock the door.
Kelli walked across the street to the gas station’s payphone to call her boyfriend for help.
She then went inside, bought a drink, and was never seen alive again.
Kelli’s family knew something was wrong, as she had a toddler who, according to her family, Kelli never would have abandoned.
July 26 & 27, 1997: Tiffany Dobry Johnston abduction and murder
Tiffany Johnston was abducted on July 26, 1997 from a car wash in Canadian County, Oklahoma.
On July 26, 1997, Tiffany Dobry Johnston went to Sunshine Car Wash in the town of Bethany, Oklahoma. She never returned home and her car was found left behind at the car wash.
The 19-year-old's body was found the next day in a field in Yukon.
Aug. 17, 1997: Jessica Cain disappearance
Aspiring actress Jessica Cain was never seen again after she vanished in Aug. 1997.
On Aug. 17, 1997, Jessica Lee Cain went to a party at a restaurant to celebrate her performance in a high school musical.
Later, her father's truck, which she was driving, was found abandoned and operational on I-45 in LaMarque. It was along the route to her home on Tiki Island.
Her purse was left inside.
October 1997: Reece arrested and named prime suspect
William Reece was arrested for the aggravated kidnapping of Sandra Sapanaugh, five months after the incident.
The Friendswood Police Department also publicly named Reece as a prime suspect in the death of 12-year-old Laura Smither. But ultimately, no charges were filed against him in that case.
Laura Smither, 12, never came back home after going for a jog in her Friendswood neighborhood on April 3, 1997. Her body was found more than two weeks later.
In 1998, Reece was convicted for the aggravated kidnapping of Sandra Sapaugh that also occurred in 1997. He was sentenced to prison for 60 years.
In 2015, an Oklahoma State Investigative Bureau agent linked Reece's DNA to the kidnapping, rape, and strangulation death of 19-year-old Tiffany Johnston.
Months later, the OSIB charged Reece with first-degree murder and knapping for the case, while he was serving his 60-year sentence in Harris County Jail.
Reece pleaded not guilty in the case.

Reece began cooperating with prosecutors and confessed to murders in Texas. His defense attorney would later reveal that Reece admitted to the killings because a Texas Ranger had promised that prosecutors wouldn’t seek the death penalty.
The convicted kidnapper was temporarily released from state prison into local law enforcement custody to help with the searches for Jessica Cain and Kelli Cox.

June 29, 2022: William Reece pleads guilty to Texas murders
About 25 years after Reece kidnapped and killed 12-year-old Laura Smither, 17-year-old Jessica Cain, and 20-year-old Kelli Cox, the 62-year-old pleaded guilty to their cold-case murders.
Galveston officials say Reece had confessed to murdering the victims, but was careful not to provide enough evidence for the State of Texas to pursue the death penalty.
Instead, he received the maximum sentence allowed, life in prison for each case. He cannot appeal.
Reece, 62, is not eligible for parole until serving 30 years, according to the law in effect at the time of the murders.
