Garry McFadden is not your usual detective.
There are no ill-fitting blazers in his wardrobe. Instead, he’ll greet you in a pressed shirt with French cuffs and a tailored suit.
He doesn’t need to ask you about your favorite artist. Thanks to technology, he’ll know all about you before he meets you.
Most importantly, he avoids interrogation rooms. Why get a confession in a sterile room when you can get it over dinner at a diner?
“Homicide detectives do have a human side. They do have a heart,” he tells PEOPLE about his approach to investigating crimes. “Treat people equally. Give respect to everybody.”
McFadden’s personal style is highlighted in a true-crime series on Investigation Discovery, I Am Homicide, in which he stars. The show returns for its second season on Tuesday night.
In the series’ new season, viewers will get to see some of McFadden’s most unique cases, ranging from his run-in with a local white supremacist that resulted in a cross-country manhunt to a harrowing murder where the only witness was a 3-year-old child.
A retired detective from Mecklenburg County in Charlotte, North Carolina, McFadden has solved nearly 700 homicide cases. His unusual tactics have attributed to his 90-percent success rate on the “investigations he pursues,” according to ID.
His commitment to building relationships with victims, suspects and his community started at an early age, when he was about 12 or 13, as he witnessed law enforcement mistreating his family after his uncle was killed.
“I told myself I would never treat somebody the way law enforcement had treated me and my family that day,” McFadden recalls. “Once I came to be a homicide detective, that was my drive — to be very personal with the family, to be understanding with the families and to put families first.”
In an exclusive clip from the premiere, McFadden shares another bit of the wisdom he learned from years on the job: “As all good homicide detectives know, sometimes you need to shut your mouth and just be quiet and listen.”
I Am Homicide‘s second season premieres Tuesday (10 p.m. ET) on Investigation Discovery.
