In 2012, 19-year-old Stevie Bates vanished after calling her mother from a Greyhound bus during a layover in Pittsburgh; she made it back to New York but never made it home. Eight years later, her skeletal remains were discovered wrapped in a blanket at an abandoned house in Queens, the same property where her boyfriend had reportedly been squatting. In this episode of Zone 7, Sheryl McCollum welcomes Stevie’s cousin, Isis Jannierre, to discuss who Stevie was, what her family believed from the beginning, and why the case still raises questions about the timeline, suspect behavior, lost investigative time, lost evidence, and the people who may still know what happened.



Highlights:

(0:00) Sheryl McCollum opens Zone 7 with Stevie Bates’ 2012 disappearance, her final call home, and the Port Authority sighting that confirmed she made it back to New York

(1:15) Isis Jannierre joins Zone 7 to establish Stevie’s victimology through the eyes of her family

(2:30) Who Stevie was: a gifted student, creative thinker, devoted daughter, and young woman with aspirations

(5:15) Hunter College, Occupy Wall Street, and the independent life Stevie was building before she vanished

(6:45) Eight years later, Stevie’s skeletal remains are found wrapped in a blanket at an abandoned property in Glendale, Queens

(7:30) Why Stevie’s family never believed she intentionally disappeared

(11:45) Decomposition, lost evidence, and the unresolved questions of how Stevie died

(12:30) Isis pushes back on the drug-use theory and explains Stevie’s role in Brandon Klosterman’s life

(15:30) Stevie’s plan to collect her belongings, the end of the relationship, and the family’s working theory

(16:45) Deleted messages, squatting, and behavior that raised questions around Brandon Klosterman

(25:00) The location of Stevie’s remains raises new questions about missing crime scenes, lost witnesses, and who may still know the truth

(28:30) Sheryl presses for the answers Stevie’s family deserves: a clearer timeline, a confirmed alibi, and an explanation for the deleted messages

https://api.omny.fm/orgs/e73c998e-6e60-432f-8610-ae210140c5b1/clips/1eb60d00-a3da-42ef-86ad-b45500fc8c27/transcript

In this week’s episode of Zone 7, Sergeant Eric McCants joins Sheryl McCollum to talk about leadership, community policing, and the mindset required to serve well in high-pressure environments. He discusses the importance of communication, building community trust, getting out of the patrol car, and knowing the people you serve before a crisis ever happens. Eric also addresses first responder mental health, the trauma that can linger after difficult calls, and why asking for help is not weakness but part of staying healthy enough to keep showing up for others.



Highlights:

(0:00) Sheryl McCollum welcomes Eric McCants to Zone 7

(4:15) “You versus you,” Extreme Ownership, and focusing on what you can control

(7:15) Policing the Masters in Augusta and managing the large crowds, traffic, and public safety

(8:45) Crime suppression, crisis intervention, and the realities of proactive policing

(10:15) Why some people need accountability, while others need help, direction, or a second chance

(13:30) Communication, rapport, and why the best officers know how to talk to people

(14:45) Why getting out of the patrol car can build trust and help solve cases

(18:15) Eric’s 12 Day Mindset Program and the power of writing goals down

(22:45) First responder trauma, therapy, and knowing when to ask for help

(25:45) Final reflections on leadership, service, and Sheryl’s closing quote from John Quincy Adams
