The first to be charged with the murders was Coleman, due to his willingness to accept a guilty plea. At the same time, authorities announced that they were investigating the pair for additional crimes, including thefts and possibly an additional murder. While examining one of the bags, determined to be Coleman's, police found numerous advertisements for dice rolling and letters he had written to women from across the country. On July 31, Brown suddenly amended his statement, claiming that he had not seen Coleman murder Mrs. Pearson, but was sure that he had killed both after he had left the house and his clothes had been bloodied. When he was informed that charges would still be brought against him, in addition to being asked why he changed his statement, Brown stated that he was afraid he would be
lynched in jail if he had been truthful. He continued to deny responsibility for Carl Pearson's murder, which he placed entirely on Brown. During the proceedings, the prosecutors presented witness testimony from several witnesses and a medical examiner, all of which substantiated the supposed robbery motive. Despite these actions, he wrote a letter to Governor
Sam C. Ford to ask whether there was a possibility of his sentence being commuted, to which Ford later wrote back and said that he would review the case at a later date.
Brown's trial Before Coleman's trial would begin, Justice C. E. Comer granted a motion by the prosecution to name him as a co-defendant in the murder of Carl Pearson. This move was criticized by Coleman's attorneys, Howard Toole and Randolph Jacobs, who claimed that it was harmful to their client's constitutional rights. In the meantime, Coleman, who was reported to play
solitaire in his spare time and occasionally
tap dance, promised that he would give reporters "the real story" shortly before his scheduled execution date. In that same time interview, he alluded that he could have easily escaped if he had accepted a ride from some white friends in
Glendive, and could have fled to
Mississippi, where he believed it was too dangerous for authorities to capture black fugitives. For Brown's trial, fifty jurors from the surrounding area were selected to preside over the trial. In the beginning of the trial, Brown's attorneys filed a motion to amend his not guilty plea, but this was denied by the judge two days later. After a week-long trial, Brown was convicted and sentenced to
life imprisonment, whereupon he was taken to the
Montana State Prison.
Change of plea A little more than a week after his trial ended, Coleman's attorney announced that he would file a motion to withdraw his client's guilty plea, claiming that Coleman would not have pleaded guilty if he had known the death penalty was on the table. This motion was denied by Justice Comer, who ruled that the initial approach was proper and did not valuate any of the convict's rights. A short time later, it was announced that two writers for
True Detective had taken interest in the case, and intended to document the entire case. And in response to the recent ruling, Coleman told in an interview with a reporter from
Missoulian that he held no hard feelings towards anybody associated with his case, and that he was fully aware and deserving of the sentence he had been handed down. ==Execution, confessions and aftermath==
