Mark Sanchez, who lives in the neighborhood and shares Ariel Castro’s affinity for the bass guitar, told The Daily Telegraph that he was at the kidnapper’s home on May 2 when he heard weird thudding sounds coming from the floor above.
Mark Sanchez also saw a little girl at one point whom he claimed he had never seen before.
Ariel Castro explained that the child was his granddaughter.
Days later, he was horrified to learn about what had been going on in the house for more than a decade.
Mark Sanchez told the paper that he would always have to arrange plans to hang out with Ariel Castro in advance – because he never answered the door if he showed up without letting Castro know first.
He told the Telegraph: “I have to say the guy was a demon but he played it real cool. It was the first time that I heard any noise.”
Ariel Castro, 52, is suspected of holding amanda Berry, Gina DeJesus and Michelle Knight captive in his home for a decade.
Authorities say he kidnapped all three women, raped them and fathered a child with one.
The women were found May 6 after one escaped and called 911.
