An Elkridge man accused of shaking his infant daughter to death pleaded guilty to second-degree murder in Howard County Circuit Court Tuesday morning, according to Howard County State's Attorney spokesman Wayne Kirwan.

Aron James Krampf, 27, of the 6200 block of Ducketts Lane, entered a guilty plea before Howard County Circuit Court Judge Timothy McCrone, Kirwan said.

Howard County police and paramedics responded to Krampf’s residence about 12:45 p.m. on Sept. 10 for a report of an unconscious, 6-week-old infant who was not breathing. Krampf’s  daughter, Aubrey, was transported to Johns Hopkins Children’s Hospital, where she died as a result of her injuries on Sept. 11, according to police.

Kirwan said at the plea hearing, Assistant State’s Attorney Jennifer Ritter read medical findings from attending doctors and the Office of the State Medical Examiner, who concluded that the child’s injuries were compatible with non-accidental trauma.

Kirwan said McCrone revoked Krampf’s bond and set a sentencing date of July 24. Kirwan said Ritter said prosecutors will seek a 20-year prison sentence for Krampf.
