LEWISTON, (AP) — A parolee from a manslaughter con viction pleaded innocent in mu nicipal court today to a charge of murder in the stabbing of a housewife he claims once was his sweethe art. Husky Joseph A. “Blacky” Lev esque, 37, was held without bail in the death of Mrs. Marguerite Couture, also 37, in the bedroom of her home yesterday. Capt. Ralph Fraser testified Levesque told him he stabbed Mrs. Couture in the chest when she resisted his love-making. The court was told the woman died from loss of blood and flood ing of her lungs with blood. The testimony came from Dr. Robert Wakefield, associate pathologist at Central Maine General Hos pital here. Levesque was paroled from the state prison two months ago after serving more than eight of a 10 years’ sentence for manslaughter in the beating of a companion in 1951. Before his arraignment Leves ue told a Lewiston Evening ournal reporter that he and Mrs. Couture had been sweethearts as teenagers. “I was in love with her once,” he said. Fraser told newsmen Levesque met Mrs. Couture’s husband, Mau rice, in a bar Saturday night and Couture invited him home. They drank beer with Mrs. Cou ture for a while and then the hus band went to bed. The couple's two children were sleeping in another room. Police quoted Levesque as say ing he followed Mrs. Couture when she went into a bedroom a short time later and started making love to her.” When she resisted, he said, he pulled a jacknife from his pocket. “I don't know what happened,” Levesque was quoted as saying. “I just lost my head. He ran from the house after the incident and told some neighbors what had happened. Levesque was imprisoned for manslaughter in 1952 for the fatal beating of Alfred Bolduc, 61, in a one room shack the men shared in the outskirts of Lewiston. Police said the men had been drinking canned heat and bag rum for several days before Levesque beat the older man with his fists. A medical examiner said he died of a ruptured spleen but that acute alcoholism was a con tributing factor.
