A Maryland appellate court has overturned the murder conviction of Michael Maurice Allen Sr., who is serving life in prison for fatally stabbing his girlfriend in 2018. The court found a prosecutor and a judge violated Allen’s constitutional right to remain silent during his trial. The prosecutor told jurors that Allen’s decision to stop answering a detective’s questions about the death indicated he was guilty. The judge overruled an objection by Allen’s defense attorney and did not tell jurors to ignore that remark. The appellate court’s decision means Allen can be retried.
