AUGUSTA — An Augusta man was sentenced to 18 months in jail Friday with all but four months suspended and two years’ probation after he was convicted of aggravated criminal trespass and aggravated assault.

Richard E. Brann, 44, of Augusta, was accused of harming a man while burglarizing his residence and stealing his liquor Nov. 12.

Charges of burglary, theft and criminal mischief were dismissed in exchange for the plea in Kennebec County Superior Court.

Assistant Attorney General Deborah Cashman said previously that the case was investigated by Maine State Police because Brann’s mother, Dorothy Joanne Brann, 74, who lived in the same building, was injured when she went to look into the disturbance. She died Nov. 22 at Maine Medical Center in Portland.

Brann’s attorney, Stephen Bourget, said later Friday that Brann and the man whose apartment he is charged with burglarizing had fallen down the stairs onto Brann’s mother, and that she died of complications.

“He has changed his life around since his mother died,” Bourget said. “He was joking around, it got of out hand, and he is devastated.”

Several other people pleaded guilty to various charges in separate hearings Friday in Kennebec County Superior Court.

• Clinton Bates, 37, of Sidney, two counts of theft by unauthorized taking, May 20, 2012 in Manchester and May 22, 2012, in Waterville; 60 day jail sentence, $125 restitution.

• Samuel D. Caison, 29, of Farmingdale/Whitefield, terrorizing May 19 and two counts of criminal attempt to violate conditions of release July 17, all in Augusta; three-year prison sentence concurrent to a 40 month probation revocation.

• Milton E. Libby 18, of Augusta, 30-plus miles over the speed limit in Gardiner Feb. 21; 30 day jail sentence, $500 fine.

• Haley J. Wormwood, 30, of West Paris, theft by unauthorized taking or transfer and violation of condition of release April 1 in Monmouth; 60 day jail sentence, $700 fine.
