HALIFAX -- The case against the "Internet Black Widow," the elderly woman who gained notoriety for killing and poisoning men who were her intimate partners, has been adjourned until early next month.

Police have alleged 80-year-old Melissa Ann Shepard broke the conditions of a peace bond in April after an officer saw her using a computer at the Halifax Central Library.

Shepard was charged with three counts of breaching a recognizance, including a ban on accessing the Internet.

The case returned to Halifax provincial court Wednesday, but Crown lawyer James Giacomantonio said the defence asked that the case be adjourned.

The Halifax resident, who was not present at Wednesday's hearing, has a history of offences dating back to the early 1990s.

She was released March 18 after having served a full sentence of just under three years for spiking newlywed husband Fred Weeks's coffee with tranquilizers in 2012.

A court imposed 22 conditions on her, including that she keep the peace and be of good behaviour.
