Lawyers in a Harford County murder case want to suppress the tearful confession of a Joppatowne librarian accused of stabbing her husband during a drunken argument, insisting she was too impaired for her statements to be admissible in court.

Eveline Anna Maria Bergmann is charged with killing her husband Jeffrey as the result of an argument last December, and defense attorney Timothy Gunning argued during pretrial motions Wednesday that her confessions to deputies and detectives from the Harford County Sheriff’s Office should be excluded from her trial.
