One of my own characters, for a possible movie.

Background:
Colton Gray is a 35 year old man. When he was a young boy he saw his own father brutally murdered by a gang member, this horrifying experience scarred him as a young boy and he grew up wanting to exact revenge. Knowing he could not do so, he joined the local police force so he could stop things like that happening to other people. But after five years of service his mother died, she was found dead in the family home with a slashed throat and hanging in the bathroom. Colton came across the body himself and had a mental breakdown, he tried for a year to get permission to lead the case of his mother's death, but to no avail. Due to it being labbelled as a suicide attempt. Colton was then fired by his force under the impression he was psychologically effected by the event and was not in the right state of mind to continue working as a lawman. In a fit of anger he went hunting for answers and eventually the killer came back, to kill him. Unknown to him it was because his father was a drugs importer and was in league with a mexican crimelord. Colton then found out he had also murdered his father, so in revenge Colton brutally murdered the crimelord and became a wanted man both by the authorities and the crimelord's associates. Cole then fled to Eastern Europe and made his living from being a hitman. Originally he would kill anyone for any sum of money, but since staying in Eastern Europe for 3 years he has come back to America and has long been forgotton about and now hides his Identity under the name of "Taylor Grant" He now currently works as an assasin taking out those who actually deserve to die and has somewhat become a shadowy figure often reported in the news yet no one actually knows what he looks like or who he is. Recently he has considered going back to Eastern Europe to kill his former contractors, whom mostly consisted of mobsters and corrupt political figures. Who knows... will he continue his fight for redemption and right or will he turn back to issue revenge to those who corrupted him?
