New details on a story we've been following since October.
The Grand Junction Police Department says they've finished the investigation into the deadly shooting on Chestnut Drive where Stephan Martin-Urban killed Dr. Terry Fine and Flo Gallagher before killing himself.
The police department has been analyzing the crime and gathering evidence to try and figure out a motive for the violent act.
They worked with the FBI's Behavioral Analysis Unit and found that the shooter acted alone, he left no note or journal that indicated his plans to commit this crime.
The victims were completely random, he had no association or connection to them.
And Stephan Martin-Urban gave no indications that he intended to commit this act.
Because of this, police say the motive was only known by him.
The report just released says that law enforcement's actions on that day were immediate and efficient.
There was a lot of emphasis on Stephan Martin-Urban's video game habits.
Police say there is not sufficient evidence to link those habits to a motive for the crime but they may have provided the shooter with an idea of how to carry out the act.
Grand Junction Police Chief Bill Gardner says that Martin-Urban became obsessed with violence and evil readily available on video games and the Internet.
Gardner says we can only hope this awakens parents and families to the threats posed to young people's minds through their home computers.
