Timeline of events in the New York kayak murder case

— -- Angelika Graswald, a 37-year-old Latvian native who was accused of killing her fiancé during a 2015 kayaking trip on the Hudson River in New York, was released from prison in December after serving just over two and a half years behind bars.

Graswald was originally charged with second-degree murder and second-degree manslaughter in 2015 and had pleaded not guilty to both charges. Weeks before the case was set to go to trial, Graswald reached an agreement with prosecutors to plead guilty to the lesser felony charge. She has always maintained she never intended to kill Viafore and that his death was a tragic accident.

Here is a timeline highlighting some of the key events in this mysterious case:

Graswald comes to the United States from Latvia to work as a nanny. Graswald told ABC News "20/20" in a 2015 interview that she "came originally for a year. But I ended up staying. You know, they say that there is a one-way ticket to America and that was my case."
