A crazed ex-husband who shot dead a mother and daughter before turning the gun on himself while searching for his ex-wife had 13 guns in his home.
Mark Bombara, 63, broke into Jennifer Petelczyc’s home in Floreat, in Perth’s western suburbs, about 4.30pm on Friday, looking for his ex-wife Rowena.
Unable to find her, Bombara shot dead his 53-year-old friend and the woman’s daughter, Gretl Petelczyc, 18, before turning the gun on himself.
Police raided the 63-year-old’s Mosman Park home on Saturday following the horrific double murder suicide.
Weapons were seized at the home, including long firearms and at least two handguns, all legally registered to Bombara.
Police confiscated 13 guns from Mark Bombara’s (pictured) home following the double suicide.
Bombara was looking for his ex-wife when he shot and killed Jennifer Petelczyc and their daughter Gretl at their home in Floreat before turning the gun on himself.
Bombara had purchased the $4.58 million two-story home on Hutchinson Avenue with his then-wife in 2019.
A friend of Petelczyc’s family told Daily Mail Australia that the mother of two had confessed to him that she feared for her family’s safety after learning that Bombara was driving with a Glock under the seat of her car while looking for her ex wife.
Rowena had been staying with Petelczyc on and off since she fled home in April amid a bitter separation from her husband.
The family friend said Petelczyc told her mother she wasn’t sure if she should tell her children that Bombara was a threat to their safety.
She said her mother urged Petelczyc to tell her two daughters, Gretl, 18, and Liesl, 23, about her concerns because they were now adults, prompting the widow to reveal that the family was in danger and advise to the girls not to open the door. door.
The family friend said Petelczyc had frequently visited his parents, seeking legal advice from his father, a lawyer, on ways he could protect Rowena and her children.
She said the last time her parents saw Mrs. Petelczyc was two weeks ago and her father yelled at her as she walked down the driveway: “don’t forget to report him (Bombara driving with a gun) to the police.”
Mrs Petelczyc replied “I will” before turning around and heading home.
The family friend said they are not sure if Petelczyc had reported the matter to police.
WA Police told Daily Mail Australia they had been unable to locate records indicating Ms Petelczyc made a report to police.
The family friend said that if Bombara, who was part of a local gun club, was reported to police, he doesn’t understand how he would have been allowed to keep his firearm if there were concerns of violence.
Rowena left the house she shared with Bombara on Easter Monday, April 1, seven weeks before the double murder suicide.
Police officers were seen standing in the driveway of the property while the mother-of-four collected and removed her belongings.
Neighbors said they were unaware there had been a serious domestic dispute between Rowena and her husband. Western Australia reported.
Rowena Bombara, a mother of four, was staying with the Petelczyc family after fleeing home amid a bitter separation from her husband.
Rowena, who was often seen gardening in her garden, was described as “very friendly and helpful” and always happy to chat over the fence.
Meanwhile, her ex-husband was labeled as distant, unusual and possessing a huge ego.
In addition to guns, Bombara also had a passion for real estate and followed in the footsteps of his father, who made a name for himself as a real estate appraiser and developer.
Bombara had been involved in 38 developments carried out by his family, including serving as project director for a Highland estate in Bridgetown.
The 63-year-old specialized in buying land, rezoning it and then selling the individual lots.
His real estate interests and businesses also took him to court, including a case in which he sued his own brother, Hugo, following the sale of family land in Betram.
Bombara sent an email pressuring Hugo to back out of the transaction after his brother refused to sign a listing release for the property.
‘The latest episode shows that they are unable to make what could well be the most important decision regarding this property and for the benefit of all the owners. . . “On this basis, I request that you be removed from the decision-making process,” the email obtained by The West said.
“You may do so voluntarily by informing me immediately or I will take action in a court of relevant jurisdiction.”
Bombara also had a long battle with Western Power after the company installed power lines on one of its land parcels.
He said the move made him feel “offended” and “cheated by the system,” adding that the company owed him millions of dollars in compensation.

In 2008, the utility offered Bombara $40,000 in compensation, but he rejected the deal and demanded $19 million plus costs.
The State Administrative Court published a ruling in 2021, disagreeing with Bombara’s claims.
The court concluded that the property was considered appropriately rural and awarded Bombara a total of $18,088 in compensation, less than half of Western Power’s original offer.
Bombara attempted to argue the result before the High Court but was unsuccessful.
Earlier this year, Bombara created a website to compile the family history of his four adult children that he shared with his ex-wife.
“We also strive to compile a detailed family history for our website,” the page reads.
‘Come in, look around. If you know anything about our family history that we haven’t included, please let us know.
The website claimed to contain information about his family, along with a family photo album. However, the only photo available is one of Bombara himself.
