Court documents from a lawsuit filed by Iris Amsel against her ex-husband Guido Amsel in October 2010 show she felt she was owed $40,000, plus half the value of several pieces of equipment and vehicles the pair jointly owned.

The couple once also jointly owned a company called Euro Tech Auto Body.

Maria Mitousis, the lawyer injured in the explosion at a River Avenue law firm, represents Iris Amsel in that lawsuit.

Police said Mitousis unknowingly received an explosive device in the mail and accidentally detonated it.

Guido Amsel has been charged with attempted murder and aggravated assault in relation to that blast.

In 2010, Guido Amsel filed a statement of defence to the lawsuit brought by his ex-wife, and also filed a counterclaim listing Iris Amsel and several other defendants, including her mother, father and brother who all live in Germany.

In his counterclaim, Guido Amsel accuses Iris Amsel of failing to render invoices and receipts for cash transactions at Euro Tech, and for instead keeping the money.

He alleges that this went on for 15 years between 1993 and 2008.

As the lawsuit progressed through the legal system, Guido Amsel changed lawyers on more than one occasion.

Initially, he was represented by John B. Harvie of Myles Weinberg LLP.

In February of 2012, Guido Amsel filed a notice with courts indicating that he would be representing himself from that point forward.

In October of 2013, a lawyer named Sarah R. McEachern from the firm Orle Bargen Davidson became Guido Amsel's lawyer in the matter.

Less than a year later, court documents show McEachern removed herself as lawyer for Guido Amsel, citing a breakdown in the relationship between her firm and Amsel.

Sunday, police found and detonated a mail bomb at the offices of McEachern's firm on Stradbrook Avenue.

Saturday, a similar device addressed to Iris Amsel was found and detonated at James Automotive Finishing.

Police believe all three mail bombs are related and said they were hidden inside voice recorders sent through Canada Post.

Guido Amsel faces two counts of attempted murder, one count of aggravated assault and several charges related to explosives.

He has been in contact with lawyers from the Winnipeg firm Gindin Wolson Simmonds Roitenberg but has not formally retained a lawyer.

His next court appearance is scheduled for Thursday, July 9, at 9:30 a.m. in Winnipeg.
