Guy Gordon Marsh walked out of a Carroll County Circuit courtroom last month with his arm around his wife, just minutes after a judge convicted him of beating her during an argument.
When the couple got home, Marsh beat her again, prosecutors claimed yesterday in a motion to revoke his probation in a 1992 rape case.
"He's a dangerous and violent person," Assistant State's Attorney Kathi Hill said of Marsh, who was released from state prison in 1987 after serving 14 years on a 1973 murder conviction that was eventually overturned.
"The very evening of the day the defendant was found guilty of battering his wife . . . he further threatened, assaulted and battered Mary Ruth Marsh yet another time," the motion states.
The battery conviction alone might be enough to persuade a judge to revoke Marsh's probation, prosecutors said. But they said the alleged beating March 16 makes it more important to put him behind bars.
Marsh, 47, gained national attention when he was released from prison in 1987 after serving more than 14 years of a life-plus-10-year sentence stemming from the June 1971 murder of Charles R. Erdman during a robbery at a Glen Burnie 7-Eleven.
The conviction was overturned after a key trial witness admitted that she had lied in her testimony. Anne Arundel County prosecutors later decided not to retry Marsh because they felt that they did not have enough evidence to convict him.
Marsh is in the final year of unsupervised probation that he has been serving since pleading guilty to second-degree rape in May 1992. In that case, Marsh admitted to having sexual intercourse with a 13-year-old.
Marsh will be sentenced in the battery case June 13, and prosecutors want the probation violation case heard the same day.
Attempts to reach Marsh yesterday were unsuccessful. His attorney, M. Gordon Tayback of Baltimore, did not return phone calls.
