Here's the complete paragraph:

"On July 13, 1948, the Chicago American, a local Chicago newspaper wrote a damning article about Nuccio stating he had been brought in and interrogated as a murder suspect on numerous occasions. He had been questioned as a suspect in no less than eight gangland slayings up to that point in time. One of his suspected murder victims was Irish mob boss Dion (Dean) O’Banion, who had been murdered in 1924."

He was suspected. The story was about Dominick Nuccio...not numerous other guys. Just stop.
