TAMPA, Fla. - Missing Valrico teen Ashley Lyon and registered sex offender Steven Myers were found in Louisiana on Wednesday.
Lyon had multiple stab wounds. Late Thursday morning, her condition was upgraded from critical to serious.
Myers was listed in serious condition after stabbing himself in front of law enforcement officers.
The Iberville Parish Sheriff's Office in Louisiana notified Hillsborough County Sheriff's Office around 1 a.m. that Lyon, 16, and Myers, 41, had been located.
Lyon was reported missing June 11 and was suspected of traveling with Myers.
The pair were recognized by a cashier at a Louisiana shop they entered.
"There's so many parents out there that have missing children that have been missing for 20 years, and they still don't know where they are," she said. "At least they're alive. They have some sort of closure. They know where their daughter is now."
The disappearance, according to a Hillsborough Sheriff's Office spokeswoman, was planned. The two apparently knew each other through Myers' children, according to Col. Donna Lusczynski.
At a news conference Thursday afternoon, Lusczynski said the two were traveling in a truck stolen in Taylor County, Fla. The truck that Myers was originally driving has not been located.
Due to media attention, patrons at a truck stop in Grosse Tete, La., notified the Iberville Sheriff's Office when they recognized Myers and Lyon as they walked in.
Lyon was recognized even though she had made what Lusczynski described as a "slight change" in her appearance. "I believe she had dyed her hair darker," Lusczynski said.
Deputies arrived to find the pair in a Chevy 3500 flatbed pickup truck and attempted a traffic stop.
Myers refused to pull over and deputies began a 40-mile pursuit.
Douglas Fremin was driving to work when he saw the chase. "I was just getting onto the exit when I saw all the police fly by right in front of me," he said. "There was cops flying by like crazy. They had about 50 cops."
During the pursuit, Myers reportedly struck four other vehicles. Deputies believe he was trying to create a road block behind him.
Deputies managed to deploy multiple stop sticks and were successful in deflating the truck's tires.
Myers continued driving on the rims, until the truck could no longer travel. "I thought maybe police had shot the tires," said Fremin, "because they were riding on two rims, and the back of the truck was on fire."
Once stopped, Myers got out of the truck with a knife in his hand, yelling at the deputies to shoot him. Fremin said, "He just got out and the first thing he said was 'Can you please shoot me?'"
When officers didn't respond, Lusczynski said Myers began stabbing himself in the abdomen. The officers then took him down.
Fremin said Lyon then got out of the truck. "She opened the door and she got out and she just put her hands up," he said, "and the cops arrested the guy and grabbed the girl."
Lusczynski said Hillsborough investigators were told by authorities in Louisiana that Lyon had been stabbed four times in the front torso and two times in the back.
Lyon's father, Roger Lyon, attended Thursday's news conference and thanked the media. He also gave much credit to social media to getting the word out about his missing daughter.
Roger Lyon acknowledged that his daughter is bi-polar and did not take her medications with her when she disappeared.
"When she went missing, we knew that she didn't have her medication with her, which is a grave concern to us only because of the effect it can have on her mental state," Roger Lyon said. "The way I understand bi-polarism, the effects on that mental state would make her especially vulnerable to someone of a predatory nature."
Lusczynski said investigators from Hillsborough County will travel to Louisiana to meet with authorities there and speak with Ashley Lyon.
Louisiana authorities plan to charge Myers with attempted first-degree murder and resisting arrest.
In Hillsborough County, he had been wanted on charges of interference with child custody, attempted unlawful sexual activity with certain minors and traveling to meet a minor.
Additional charges are likely in both Florida and Louisiana, Lusczynski said.
