Anyone know what happened in Fremont tonight that caused CSI to be dispatched?

On NW 44th St near the intersection of Leary and 8th Ave NW. At 9:30 PM, there were 2 SPD cars and a CSI unit set up around a rundown camper van, spotlights set up on the van which police were searching. Unsure how long they’d been there. My partner and I also both thought we’d heard a noise that could have been a gunshot around 8 PM, I think.
