A Bridgeport, Conn., man branded as one of the two true killers of 15-year-old Martha Moxley — a crime for which Michael Skakel was convicted and is serving prison time — has denied any involvement in the 1975 murder and said Sunday he didn’t know why Skakel’s defense team was “dragging my name into this mess.”

The man, now 43, confirmed that he spoke with Skakel investigator Vito Colucci recently and provided a phone number that Colucci requested.

“I had nothing to do with this,” the man said during brief comments he made through a screened window at his home.

Asked whether he killed Moxley, the man replied, “Of course not.”

Skakel’s new defense team of Hope Seeley and Hubert Santos suggested for the first time Thursday that they had uncovered new evidence showing that Skakel, 42, was wrongfully convicted of Moxley’s murder. He was sentenced last August to 20 years to life in prison.

The Hartford Courant learned Friday that the new evidence was based on a 90-minute videotaped interview Colucci did with Gitano “Tony” Bryant, who attended the private Brunswick School in Greenwich, Conn., with Skakel and several other residents of the gated Belle Haven community of Greenwich where the murder occurred. Bryant said two friends from the Bronx borough of New York, who occasionally partied at Belle Haven with him and others, were at Belle Haven the night of the murder and later admitted to him that they were involved in the killing.
