BATH — A Bath man who was convicted in 1992 of manslaughter in the stabbing death of a Massachusetts man is going back to prison – possibly for as long as 30 years.

District Attorney Geoffrey Rushlau said a Sagadahoc County jury has convicted 51-year-old James M. Manley of Class A elevated aggravated assault.

The jury, which deliberated for seven hours over  two days, found Manley not guilty of terrorizing with a dangerous weapon and obstructing the report of a crime.

Manley was arrested last September on a charge that he repeatedly stabbed a Bath man during a confrontation that took place in an apartment on Middle Street.

The victim suffered several stab wounds, including one that severed a nerve in his arm. The victim has limited use of that arm.

According to Rushlau, Manley was convicted in Worcester County, Mass., on April 22, 1992, of killing another man. He received a sentence of 10 to 20 years in prison, completing his sentence in 2002. Manley was also convicted of assault with a deadly weapon (a knife) in Boston in 2009.

Rushlau said Manley’s violent criminal record mandates that he ask that Judge Andrew Horton impose the maximum sentence of 30 years.

Manley will be sentenced at a later date.
