A Stamford man whose tongue was partially bitten off as he tried to rape a woman has been found not guilty by a Connecticut judge ruling he was insane at the time of the assault.

The Stamford Advocate reports that Superior Court Judge Richard Comerford said prosecutors proved beyond a reasonable doubt that the 48-year-old Gerard Landon sexually assaulted a woman at a church in June 2011.

He says Landon has psychiatric problems dating to 1988 and has been diagnosed with Schizophreniform disorder.

Landon's lawyer, public defender Howard Ehring, said Comerford made the right decision.

A Stamford psychiatrist testified that Landon had not been taking anti-psychotic medications.

Comerford said Landon, who is jailed, must be confined by the state commissioner of mental health for further evaluation.
