LAS VEGAS (KTNV) - It took 10 months for the Las Vegas Metropolitan Police Department team assigned to the 1 October investigation to sort through all the evidence and issue a final report.
During that time, the six detectives on the team watched hundreds of hours of body-camera footage from officers, along with witness videos from the Route 91 Harvest Festival concert guests.
"Toughest case we've ever worked. Any of us," said Sgt. Jerry MacDonald with LVMPD's Force Investigation Team.
Those 10 months were hard on every member of FIT who had to work long days searching for a motive that never presented itself.
"I don't think that is something you can put into words. It weighs heavily on you and is in the front of your mind," Det. Trever Alsup said.
While the investigation consumed their lives for much of the time, the detectives, like much of the Las Vegas community, found a way to help lift their spirits just nine days after the horrific attack.
The detectives, like much of the grieving community, say that moment instantly bonded them to the #VegasBorn team.
"Really it is just the way the whole organization handled that night and what they did," Alsup said. "Taking the ads off the boards and putting Vegas Strong. The way they rallied around this community."
"It seemed like they really cared about the community which made a big difference," Det. Marc Colon said.
As the days continued and the investigation demanded more of their times, it was the Golden Knights success that helped the most.
"It was just a little break from our normal everyday job," Colon said.
They spent a few minutes recounting Marc-Andre Fleury's fantastic saves and William Karlsson's unbelievable goals on the other heroics from the Golden Misfits.
