A Cornville man with a long history of terrorizing and threatening in Somerset County has been indicted by a Kennebec County grand jury on felony assault charges for assaults allegedly committed at the Riverview Psychiatric Center in Augusta.

James L. Mayo, 45, who has been housed at the Somerset County Jail since shortly after his release in June from Riverview, is charged by the grand jury with two counts of assault on March 29 in connection with incidents that occurred while he was still a patient at the Augusta hospital. The charges are class C felonies, each punishable by up to five years in prison. The indictments had been sealed until recently.

Mayo was housed briefly at the Kennebec County jail in Augusta, but since has been returned to the Somerset County Jail. He is being held without bail on a probation violation in Somerset County and in lieu of $1,000 unsecured bond for the Kennebec County charges, according to a jail intake worker at the Somerset County jail.

The date of the new indictment is July 21.

A probation hearing in Somerset County was continued earlier this month to Wednesday because Mayo has no place to live outside of jail. His court-appointed lawyer, Phil Mohlar, of Skowhegan, did not respond to requests for comment on the case Friday.

District Attorney Maeghan Maloney said in an email Friday morning that there may be a place for Mayo to go in Portland and that an interview had been scheduled for Friday. Maloney did not return messages later in the day Friday to say whether that interview took place.

Mayo was sent to Riverview in November after he was deemed incompetent to stand trial on terrorizing charges. Mayo later was found competent to face the felony terrorizing charge in June after months of treatment at Riverview. He pleaded guilty to the charge June 29 and was sentenced to two years in prison, with all but eight months and 25 days suspended. He was released the same day — June 29 — because he already had served the eight months and 25 days in the county jail and at Riverview.

Mayo is no longer a patient at Riverview. He is serving two years of probation as part of the terrorizing plea. He has been ordered by the court to maintain his medication plan as part of his probation.

Mayo was arrested July 6 after he allegedly failed to show up at Riverview for a scheduled doctor’s appointment after his release from the hospital and for allegedly failing to meet with a probation officer within 48 hours of his release.

He was out on probation when the doctor’s appointment was missed, but when state corrections officials saw the conditions he was living in, they asked that his probation be revoked until satisfactory living conditions could be found for him.

In documents filed in court in Skowhegan, it was noted that after Mayo’s release from Riverview, he was living with his mother in Cornville in a small room with no bed. He was sleeping on the floor, according to the court files. The recommendation is that Mayo be held without bail until “adequate housing, medical, mental health and pharmaceutical services can be established.”

“Without a proper plan in place, this client has shown on multiple occasions that he will fail and public safety would be at risk,” court documents read.

Mayo was arrested in early October for threatening to kill a family of three in Skowhegan and to shoot police if they were called. He was arrested a second time that weekend for breaking bail conditions by drinking alcohol, police said. It is that terrorizing charge that he pleaded guilty to June 29, according to court records.

Even with a proper plan in place, state corrections officials still want to keep an eye on Mayo, who has been convicted three times in recent years of terrorizing and threatening people. Mayo was convicted twice before on threatening and terrorizing charges. He was convicted of criminal threatening with a dangerous weapon in December 2012 and terrorizing in March 2014.
