A man from South Dakota has been sentenced to seven years in prison connection with the death of a homeless man whose body was found on fire in Bangor back in 2006. Kenneth Bruning of Rapid City, S.D., entered a plea in a Bangor courtroom Friday on a manslaughter charge. As part of deal called an Alford plea, he pleaded guilty, saying the prosecution has enough evidence to convict him, but he did not admit guilt. The body of 36-year-old Trevor Sprague was found in flames under the Kenduskeag Steam bridge.Evidence presented in court on Friday showed Sprague was strangled first and was not alive when his body was set on fire. With the plea, a murder charge against Bruning was dropped. A murder conviction carries a maximum sentence of life in prison. A manslaughter conviction carries a maximum of 30 years in prison.Bruning was given credit for the 14 months he’s already served since his arrest.
