stenciled gang signs

In this episode of CSI, a key witness in a gang murder was found in his car shot and the entire car burned, with the same gang sign spray painted on the car as in the murder he was going to provide commentary on. During the investigation into his death certain pieces of evidence that were at first thought to point to the gang in conjunction with the murder started to look fishy. The wife of the murdered witness was questioned as to why she was not in the car with her husband when he was shot since they were having dinner at her parent’s house and needed to go home. She confessed that they had been in a fight and had not gone home with him. Once the wife was out of the suspect list the crime scene investigators found that the so-called gang sign spray painted onto the car was actually stenciled on and then painted over to look free hand. The paint used was also specialty paint and not cheap spray paint. This led to an investigation into the contents of the murdered witness’ father in-law’s house and garage. During the investigation a stencil was found with the same lettering and paint that was on the car. The shot was also found to have been from a gun the father in-law had recently given the murdered witness. The shot was by mistake after the car had heated up. This episode seemed fake in regards to the thoughtlessness of the father in-law not getting rid of compromising evidence to the murder. Also the circumstances of the murder seem not possible when you find out the fire started in the car and heated the gun, this makes it seem like the murdered witness could have gotten out of the burning car.
