A woman accused of killing the father of her child over a custody dispute in Longmont will head to trial in February. Trial had been scheduled to start this month, but was delayed. Devan Schreiner, 27, faces first-degree murder charges in the death of Jason Schaefer. Schaefer was delivering mail in Longmont when he was shot to death in October of last year. Schreiner and Andrew Ritchie are accused in the murder plot. Schreiner has pleaded not guilty. Right now, cases against Schreiner and Ritchie are being tried separately, but a judge is considering merging the cases.
