One of the three women who went missing about a decade ago and apparently endured years of captivity knew the man suspected of kidnapping her, according to her family.
Family members of Gina DeJesus told CBS Cleveland affiliate WOIO-TV that Ariel Castro was a relative of DeJesus' best friend, possibly her father.
Castro has also been to at least two vigils for the missing girls, the station reported.
Crowds gathered Monday night on the street near the home where the city's police chief said he thought DeJesus, Amanda Berry and Michelle Knight had been held since they went missing when they were in their teens or early 20s.
On a recorded 911 call Monday, Berry frantically declared, "I'm Amanda Berry. I've been on the news for the last 10 years."
She said she had been taken by someone and begged for police officers to arrive at the home on Cleveland's west side before he returned.
"I've been kidnapped, and I've been missing for 10 years," she told the dispatcher. "And I'm here. I'm free now."
Berry disappeared at age 16 on April 21, 2003, when she called her sister to say she was getting a ride home from her job at a Burger King. DeJesus went missing at age 14 on her way home from school about a year later. They were found just a few miles from where they had gone missing.
Police said Knight went missing in 2002 and is 32 now. They didn't provide current ages for Berry or DeJesus.
