Legal troubles flared back up Thursday for Ryan Michael Larson, the initial suspect arrested and then released in the shooting death of Cold Spring police officer Thomas Decker.

An arrest warrant was issued and felony stalking charges were filed in Wright County, accusing Larson of harassing an ex-girlfriend with e-mails and texts -- including some alleged e-mail contact with her the night Decker was killed. Larson has insisted he was at his Cold Spring apartment by 6 p.m. on Nov. 29 and asleep at 8 p.m., waking after midnight when police officers arrested him.
