In a hail of bullets that day on April 9, Safwan Charbaji was killed and 25-year-old Abdullah El Masri wore a bullet to the jaw. Three weeks later, in what may have been an act of retribution, feared standover man and crime figure Walid "Wally" Ahmad was executed. Crime figure Walid "Wally" Ahmad, who was killed outside Bankstown Central shopping centre in April. At the heart of this union on an industrial cul-de-sac in Condell Park, where 41-year-old Wally wheeled and dealed, was a dispute worth $100,000. But where that lucrative bundle of cash comes from is a question that has detectives scratching their heads. They know who pulled the triggers that day on April 9, but a clear motive has been clouded by theories self-serving stakeholders have pushed and a network of fluid criminal networks.

What is known is that on the afternoon of Saturday April 9, members of the Elmir network turned up to Wally's A Team Body Works business. Wally Ahmad's business, A Team Body Works in Condell Park. While Wally's name was not on business records – as he told whoever would listen, that meant he couldn't be pinned for anything – it was widely known he was the boss. He roared up and down the street in expensive cars, including a $400,000 SLS Mercedes, and loudly played out his grievances without a care of who heard.

As one officer put it, he did the hard years early on to earn the reputation. People were bashed to a pulp inside the workshop but if the melees didn't stay behind closed doors the driveway sufficed.

Insights into his softer side included walking hand-in-hand with his young daughter down the street to buy ice cream. Wally's stronghold extended not just over his smash repairs but over the street.

Mahmoud "Brownie" Ahmad left Australia and travelled to Lebanon after a shooting at his brother's Condell Park smash repairs business on April 9. Or so Wally told the staff at a nearby shop when they dared to ask him about that outstanding $400-$500 tab he clocked up for cigarettes. "I own this f**king street," screamed Wally, as a local later recalled. The funeral of Walid "Wally" Ahmad at Lakemba Mosque. This must have been abundantly known when the Elmirs – a criminal network whose softer approach to extortion gained them the nickname "the Robin Hoods" – drove into Ilma Street.

On the Elmir side that day was the patriarch, Fawaz Elmir, five months out of prison after doing time for a cocaine supply conviction.

One theory being investigated is whether a staged kidnapping sparked the meeting. Fairfax Media has been told that this theory involves Wally's brother, Mahmoud "Brownie" Ahmad, secretly colluding with one of the Elmir network's relatives to concoct a fanciful kidnapping. Crime figure Walid "Wally" Ahmad was shot dead at a Bankstown shopping centre on April 29. The Elmir relative would pretend to be a hostage of the Ahmad network, who would only release him if they received $100,000. This demand was conveyed to the Elmir network. However, instead of handing over the cash, the Elmirs drove over to confront Wally and his brothers, sparking the gun fight.

Fairfax Media understands the fake captee has gone to ground with both his own contacts and the Ahmads keen to find him. Another theory circulating, and one that demonstrates the capricious nature of these organised crime relationships, involved the Elmir and Ahmads initially working hand in hand. The story goes that the Ahmad network recruited the Elmirs to do a courier run of cash – again of $100,000 An iPhone was placed in with the bag of cash and one of the Ahmads fired up the application Find My iPhone to track the cash transit. When the car was parked, the Ahmads stole the cash back and then blamed the Elmirs for losing it, sparking the confrontation.

While other underworld sources say the two families were already on bad terms because Stephen Elmir allegedly slapped one of the Ahmad brother's sons at karaoke and had to pay $50,000 to smooth it over. Mention of the Ahmad family name commands an ill-gotten connotation of respect in the south western suburbs. Wally's closest mate at the time was, Auburn man Monzer El Husseini, who had the house of his mother, aunt and his own shot up in drive by shootings more than a decade ago after falling out with a notorious crime family. Investigators have cited this as an example of the same revenge that could be carried out for the most recent shooting, Up to five guns were involved in the Condell Park shooting and police suspect they know at least two people who fired them – Fawaz Elmir and Brownie Ahmad.

The violent and unpredictable Brownie left the country for Lebanon in the days after the confrontation but investigators suspect he also fired a gun. At the end of the day, Safwan Charbaji was shot in the head and chest. A former A Team Body Works employee, Abdullah El Masri, a 25-year-old who sources say was easily led astray, was shot in the jaw but survived. It is suspected Mr El Masri was an unintended victim caught in the cross fire while Mr Charbaji was a target. Mr El Masri was in Liverpool Hospital under a different name, to protect him from people like one of Wally's right hand men, who tried to visit the young man while he was in a coma. Three weeks after the Condell Park shooting, after finishing a gym session as per his daily routine, Wally was executed at a Bankstown cafe.

It was his unwavering daily routine – gym, eat, sleep, gym, cocaine, repeat – that may have paved the way for his executioner to find this crime figure and kill him so brazenly. The Condell Park shooting is an obvious motive for Wally's demise. Yet with a criminal career that saw many hard-working business people succumb to his demands, it is possible someone used Condell Park as a cover for seeking their own revenge.
