WASHINGTON — It’s been two years since Sarah Hoggle, 3, and Jacob Hoggle, 2, disappeared. The Clarksburg, Maryland, children have not been found. Their mother remains in a maximum-security psychiatric hospital in Jessup, Maryland, since her arrest in September 2014.

Catherine Hoggle is charged with parental abduction, neglect and hindering and obstructing the investigation into her children’s disappearance, but a judge has repeatedly found her to not be competent to stand trial.

Below is a timeline of the events in the Hoggle case.
