McKINNEY (April 13, 2015) — The McKinney High School (MHS) and McKinney Boyd High School Law Enforcement Explorer Clubs hosted a Regional Explorer Competition at McKinney Boyd High School on March 21 that put students’ burgeoning law enforcement skills to the test in eight possible police response scenarios. Now, five MISD teams are headed to state.

The regional competition included seven teams from Dallas, Burleson and Irving in addition to two teams from MHS and three Boyd teams. The tasks they faced included scenarios that ranged from misdemeanor traffic stop procedures to active shooter response.

Kina Vinson, a former police officer who now teaches criminal justice at McKinney High School, brought two young and relatively inexperienced teams to the regional event and was curious to see how well they would perform in competition. The results left her pleasantly surprised.

“I couldn’t be more proud of our teams’ hard work and dedication this year,” she said. “We graduated 13 members last year and were worried about starting all over. But, even with only one returning member, McKinney High School still posed a threat at this year’s regional competition.”

Vinson’s counterpart at Boyd, Andrea King, had high praise for her own teams, “I am very proud of their performance at regionals,” King said. “They really stepped up to the plate and did an excellent job. They worked together as a team and came out successful.”

Here are the 2015 Regional Law Enforcement Explorer results for each of the MISD teams:

  • MHS Team 1 (Kendra Murphy, John Hutcherson, Angela Sinacore, Andrew Harper):
    • First in Traffic Accident Investigation (Scenario A)
    • Second in Felony Traffic Stop (Scenario B)
  • MHS Team 2 (Mya Emerus, Zach Vernier, Nick Kerekgyrto, Christopher Fierro):
    • Second in Intoxicated Driver
    • Third in Domestic Crisis Intervention
    • Zach Vernier — Third in Physical Agility Course
  • MBHS Team 1 (Nicholas Marshall, Rianna Elliott, Carly Crane, Arin Umlauf):
    • First in Misdemeanor Traffic Stop (Scenario A)
    • First in Felony Traffic Stop (Scenario A)
    • Third in Crisis Negotiations
    • Third in Active Shooter
  • MBHS Team 2 (Maddie Wilhite, Rosely Segarra, Payton Cellars, Brendon Knight):
    • Second in Robbery in Progress
    • Third in Traffic Accident Investigation (Scenario B)
    • Third in Felony Traffic Stop (Scenario B)
  • MBHS Team 3 (Matthew Tallo, Katie Seymour, Caleb Yancey, Ilyssa Martinez):
    • Second in Misdemeanor Traffic Stop (Scenario B)
    • Third in Traffic Accident Investigation (Scenario A)
    • First in Crisis Negotiations
    • First in Active Shooter
    • Matthew Tallo — First in Physical Agility Course

On the horizon, is the state competition at the University of Texas at Arlington on July 30 through Aug. 2, and that means the teams will be working hard to tighten up procedures and prepare for more event categories.

“We’ve reviewed the score sheets [from regionals] and will be improving on some areas as well as learning the other 20 events they need to know how to handle for the state competition,” said King. “We will be continuing our weekly practices on Monday and Wednesday afternoons until the end of the school year and then we will be practicing throughout the summer every week up until competition weekend.”

While Vinson and King each have law enforcement experience, the teams also benefit from the guidance of seasoned McKinney police officers. This year, Sgt. Holmes and Officers Martin, Traynham, Bailey, McGee, Logan and Guerrero of the McKinney Police Department have all contributed their time and expertise to the effort.

Last year, Boyd won first place in Crisis Negotiation and second place in Felony Traffic Stop, and the MHS team earned third place in Bomb Threat Response at the state competition. And judging from the regional results, there’s no reason to think that they won’t do the same thing again this year.

Regardless of how young they are.

“The good part about our team being so young,” Vinson said of her MHS teams, “is that we get a chance to work with them for the next 3 years. I can only imagine how good our team will be in the future.”
