Who do the criminals initially suspect of stealing the money?  Answer the above question based on the context below:  Five men, criminals Ray, Dave, Stevie, Julian ("Julie" as a nickname), and Jason, plan a heist to steal a minimum of £2 million. Using a truck modified as a battering ram, the group break into a security depot in London and steal a large amount of money before the police arrive. However, they discover they barely got the amount of money they wanted, and only £68,000 to each man. Julian demands an extra amount of money as "expenses" for his work, but is beaten and placed in the boot of Ray's car until he just accepts his share. The group, without Julian, later spend time at a bar with fellow criminal Sonny, and Ray's girlfriend Connie, a protester. Ray and Stevie also visit an elderly couple, Linda and Bill, where they leave their stolen money for safekeeping. The next day, Ray and Stevie, who live together with Connie, are alerted by a bruised Dave that his money was stolen, apparently by Julian. Ray, Dave and Stevie investigate Linda and Bill's home to find them murdered and the money stolen, leaving Ray emotionally distraught. He visits Julian but his money is missing too. They conclude that Sonny stole the money and break into his house, only to find Jason dead with a headwound. The four are alerted to a pair of undercover police officers and flee, Dave and Julian engaging in a shootout with the police. Believing that he may be arrested for murder, Ray decides to flee after the money is found, and goes to his mother and Connie for help. His mother gives him some money and her car to use, disappointed in her son's career but still caring for him. Ray then speaks with Connie and asks her to come with him, and to meet her at a roadside service station on the M1 if she decides to come.
