Most everyone in the neighborhood knew Ariel Castro.
Neighbors say he played bass guitar in salsa and merengue bands and gave neighborhood children rides on his motorcycle.
Tito DeJesus, an uncle of Gina DeJesus, played in bands with Castro over the last 20 years. He recalled visiting Castro's house but never noticing anything out of the ordinary.
Juan Perez, who lives two doors down from the house, said Castro was always happy and respectful. "He gained trust with the kids and with the parents. You can only do that if you're nice," Perez said.
Castro also worked until recently as a school bus driver.
He was friends with the father of Gina DeJesus, one of the missing women, and helped search for her after she disappeared, said Khalid Samad, a friend of the family.
"When we went out to look for Gina, he helped pass out fliers," said Samad, a community activist who was at the hospital with DeJesus and her family on Monday night. "You know, he was friends with the family."
Antony Quiros said he was at the vigil about a year ago and saw Castro comforting Gina DeJesus' mother.
One neighbor, Francisco Cruz, said he was with Castro the day investigators dug up a yard looking for the girls.
Castro told Cruz, "They're not going to find anyone there," Cruz recalled.
Cleveland police now are conducting an internal review to see if they overlooked anything.
City Safety Director Martin Flask said Tuesday that investigators had no record of anyone calling about criminal activity at the house but were still checking police, fire and emergency databases.
Two neighbors said they called police to the Castro house on separate occasions.
Elsie Cintron, who lives three houses away, said her daughter saw a naked woman crawling in the backyard several years ago and called police. "But they didn't take it seriously," she said.
Another neighbor, Israel Lugo, said he heard pounding on some of the doors of the house in November 2011. Lugo said officers knocked on the front door, but no one answered. "They walked to side of the house and then left," he said.
"Everyone in the neighborhood did what they had to do," said Lupe Collins, who is close to relatives of the women. "The police didn't do their job."
Police did go to the house twice in the past 15 years, but not in connection with the women's disappearance, officials said.
In 1993, Castro was arrested two days after Christmas on a domestic-violence charge and spent three days in jail before he was released on bond. The case was presented to a grand jury, but no indictment was returned, according to court documents, which don't detail the allegations. It's unclear who brought the charge against Castro, who was living at the home from which the women escaped Monday.
