AUGUSTA — The 16 letters from the inmate were addressed to his 1-year-old daughter. However, the message was for her mom: Don’t talk to the district attorney and don’t provide a contact phone number. If the district attorney can’t find you, charges against me will be dismissed.

Those letters cost Robert Vincent Johnson, 30, of the Madison/Skowhegan area, nine months in jail, which he will serve following a nine-month sentence for violating probation.

Johnson on Tuesday pleaded guilty to a charge of tampering with a victim and violating conditions of release as well as a charge of domestic violence assault from Waterville District Court stemming from an incident May 15. Assistant District Attorney Kate Marshall maintained that Johnson’s letters, sent from jail May 16-July 17, were attempts to get the victim to withhold information, according to documents filed in Kennebec County Superior Court.

Lisa Whittier, Johnson’s attorney, said Wednesday that Johnson told the judge on Tuesday he was very remorseful and would learn from his experience.

“He said he was very ashamed of the way he behaved as a man and a father,” Whittier said.

Johnson has been held in Kennebec County jail since May 15.
