Jacqueline was a lawyer from Townville, friend of the Jamin family. She was murdered by one of her potential clients and before dying, messed up with a contract that ended up being the motive of another murder.
Gino Reina was patrolling in a police helicopter and he saw a body at the Jamin Fields (which were called like that because they were the first terrain that belonged to Jamin Family Company). The player and Evan Day went to investigate the case and found out that the victim was a woman called Jacqueline Ramos who had been shot in her chest.
Barbara Thacks, a well-known thief, was interrogated about her death and later revealed that she had been sued by Jacqueline many times. Ashley Jamin also became part of the case, who said that she was her friend. The true killer was in fact arrested later, and it was a car parts seller called Roger Andrews. He had developed a very weird and nonsensical plan to kill, which involved turning the rim of his wheels into bullets at a foundry. His motives were that Jacqueline was trying to take Roger to Court because he was selling stolen products. He was sentenced to 50 years in jail with no chance for parole.
After Roger's arrest, Ashley Jamin asked the team to find a very important contract that Jacqueline had. The team found it and saw that it was a contract for Ashley to buy the Oak Valleys, which belonged to Steve Zasts. Steve was not a good person so the police presumed that there was some kind of secret exchange behind that business. Jacqueline knew that Zasts could not be trusted, so she tore the contract up.
In this case, Steve Zasts killed Cecilia DiGiappo. Jamin Family Company was helping Cecilia and DiGiappo Farm, but they hadn't bought the Oak Valleys when Steve offered the field to them. In fact, Jacqueline had torn that contract up because she didn't want the Jamin to have businesses with Zasts because he was not a good person. Steve thought the family had looked down on him so he went to buy DiGiappo Farm but Cecilia didn't think kindly of him so she refused. Zasts blamed the Jamin for his disgrace in businesses and planned to kill all of their clients to destroy like they wanted to destroy him, and started by killing Cecilia. Evan hinted to him that Jacqueline didn't want the Oak Valleys business to be true but Steve didn't care and thought that the Jamin hated him.
