Still, investigators kept her case open and checked on it several times. Then, 19 days before the anniversary of Berry's disappearance, another girl went missing.
And Lorain Avenue was at the center of it again.
The third abduction
In March 2004, a month before the last person was abducted, Ariel Castro began having serious problems at work.
He received a 60-day suspension for leaving a child unattended on a school bus, school documents show.
Castro was facing several disciplinary issues -- unauthorized stop, failure to follow proper radio procedures, failure to effectively carry out job description activities -- but documents indicate he was ultimately disciplined for just one offense.
The police even went to Castro's house to investigate the bus incident about an abandoned child. No one answered at the home, and investigators later interviewed him elsewhere, police said.
Less than a month into Castro's suspension, the last of the three victims was abducted.
Georgina "Gina" DeJesus was barely a teenager -- just 14 -- when she vanished while walking home from middle school on Cleveland's west side. She was last seen on Lorain Avenue at a pay phone after school on April 2, 2004, a cold spring day.
In a ghoulish twist, DeJesus actually knew Ariel Castro, her family told CNN affiliate WOIO.
That's because she was a good friend with Castro's daughter, Arlene.
One year after DeJesus's appearance, Arlene Castro publicly crusaded to find her friend's kidnapper: She went on the national television program "America's Most Wanted" to plead for help in finding her friend in spring 2005.
Ariel Castro himself attended at least two public vigils for the missing girls -- while they were allegedly inside his home -- relatives told WOIO. Little did she know that her own father would later be charged with abducting and raping her good friend.
"I would like to say that I'm absolutely so, so sorry," a tearful Arlene Castro told ABC News this week. "... I'm so sorry for everything."
In fact, the police report described how DeJesus was allegedly taken: Castro was with his daughter when they allegedly approached DeJesus in the area of Lorain Avenue and 105th Street.
Then Castro allegedly returned to DeJesus without his daughter and offered her a ride to his house to meet up with his daughter, the police report said.
When DeJesus disappeared in 2004, even the FBI joined the search: That's because a total of two girls had disappeared from Lorain Avenue in Cleveland. In reality, there were three persons missing. Knight was the first, but the Cleveland police had removed Knight from the FBI missing person database in late 2003. That was 15 months after she was reported missing.
Police kept the Knight case open, but 2004 news accounts in the Plain Dealer didn't include Knight in how the community was searching for only two girls who disappeared on the Lorain abduction corridor.
With two girls and one woman in his house, Castro allegedly made the captives obedient by testing them: he pretended to leave the house and then surprised them. He disciplined them if they sought to escape, a law enforcement source with direct knowledge of the investigation told CNN.
The three women feared their captor. They surrendered for years.
Personal life crumbles for alleged abductor
By late summer 2005, Castro's common-law marriage was in trouble.
At that time, court records showed the couple had separate addresses, and Castro's was his house. Records don't detail the history of the couple's living arrangements.
His common-law wife, Grimilda Figueroa, once lived in Castro's house in the Latino neighborhood on Seymour Street on Cleveland's west side, but it's unclear exactly when.
For all the time that Castro lived in his house, family wasn't allowed to venture too deep inside.
