In Pt. 1, Detective Justin gets an early morning call to respond to a community garden where a man’s body is found slumped over at the base of a tree. The first assumption is this is a tragic, but all too common suicide. But the evidence starts to tell a different story, and soon Justin finds himself hot on the trail of a murderer. Pt. 2 drops tomorrow!

Detective Dan gets called to an apartment complex to investigate a hit and run.

Famed cold-case investigator and forensic analyst Paul Holes brings us two murder cases from Northern California that remain unsolved.

Police get called to do a welfare check on a mother and son who have been unusually hard to reach. Officers arrive at the home to find the mother brutally murdered and there’s no sign of the son. Is he a victim or a suspect?

Lou is in and out of prison, but if you put him in a shirt and tie and sat him behind a desk, you’d never know that about him. It’s just one of the unique things about Lou. One day, he’s approached by a fellow inmate named Jason about a murder-for-hire. Lou immediately contacts the cops. As Det. Robert investigates he gets much more than he bargained for.

Bob is an educated and successful married man who orders up an online escort. When the escort shows up, Bob gets more than he bargained for. The police are called and a multi-state investigation ensues.

When a drug deal goes wrong leaving one victim at death’s door and two armed suspects on the run, this Small Town police department draws on their “mutual aid agreement” with neighboring agencies to help set up an extensive perimeter and conduct the manhunt. They call in K-9 handler, Justin, and his four-legged partner, Fedo, to assist. If you’ve ever doubted that a police dog can perform in ways above and beyond his human counterparts, this episode will make you a believer.

A scorned lover, a brazen suspect, an autistic witness, and good old fashioned detective work break this case wide open for Detective Dan.
