Records have shown that WA double-murderer Mark Bombara was doing deals for his multi-million dollar business interests on the same day he shot mother and daughter Jennifer and Gretl Petelczyc.

Bombara, the force behind the 300-lot Highland Bridgetown residential development at Bridgetown, 260km south of Perth, had bought and sold tens of millions of dollars worth of properties over the past twenty years, The West Australian is reporting.

The Mosman Park businessman, gun enthusiast and owner of 846ha of farm and forestry land near Quindanning was comfortably wealthy and was pursuing new ventures as he embarked on the killing spree that ended with him taking his own life.

Corporate regulatory filings have also revealed that two new companies were registered on Mr Bombara’s behalf only five hours before the shootings.

The Melbourne filings for Mach 2.0 Holdings Pty Ltd and Mach 2.0 Pty Ltd are time-stamped at 1.44pm (AEST).

It is believed Bombara arrived at the Petelczycs’ Berkeley Crescent home just before 4:30pm on Friday in search of his ex-wife, Jennifer’s friend.

When he couldn’t find her, he shot Mrs Petelczyc and 18-year-old daughter Gretl before turning his pistol on himself.

The documents filed with the corporate regulator, the Australian Securities and Investments Commission, show Bombara was the sole director and shareholder of the new companies, which were registered to his Mosman Park home.

However, there is no indication of how he intended to use them.

The documents were filed on his behalf by a Melbourne-based financial services group that specialises in products and services for sophisticated investors and self-managed superannuation funds.

Including the new additions, Bombara was a director of nine proprietary companies when he shot himself.

Five of the companies were owned in partnership with his estranged wife or outside investors.

His holdings included two-thirds ownership of a big Shell service station lot in Thomas Road, Casuarina, and a retail and office building on the corner of Point Road and Cantonment Road in Fremantle.

He also had a half share in the behind the Meldene West residential development in Donnybrook.
