Connie Oland — Dennis's mother and Richard's widow — issued a statement on Wednesday, declaring her son's innocence.
"We know that he will be found innocent in an objective and fair process in a court of law," the statement from his mother, his wife Lisa Oland, and sisters Lisa Bustin and Jacqueline Walsh states.
They and several other family members were in court on Wednesday when Dennis Oland, 45, was charged with second-degree murder.
Richard Oland was found dead in his Saint John office on July 7, 2011. He was 69.
"We wish that the police would turn their attention to finding out who is really responsible for Dick's [Richard Oland's] death," the statement says.
"We know that Dennis is innocent. We are devastated that this nightmare for Dennis and for all of us is going to continue," the family says.
The past two years have been the most difficult of their lives, they say, adding they are grateful for all the support they have received from family and friends.
Dennis Oland has not entered a plea.
He remains in custody and will return to court Tuesday to set a date for a preliminary inquiry, which will determine if there's enough evidence to proceed to a trial.
Derek Oland — Dennis's uncle and Richard's brother — also issued a statement on Tuesday, saying they believe Dennis is innocent, and they will support him and his family through these legal proceedings.
