Lestician was a longtime teacher at South Brunswick High School, and was and was named NJ.com's softball Coach of the Year in 2019 during his second season at Hightstown, NJ.com reports. Maguire was a longtime advocate for women, children and families. In her profile for Prevent Child Abuse New Jersey, Maguire wrote, "My 25+ years of experience in Early Childhood have taken me from the classroom, to center administration, to training and coaching, and I am proud to help providers through the Grow NJ Kids process." A GoFundMe set up for Maguire's daughters called her "a light." "She was fun, positive, uplifting and supportive," the page states. "Unfortunately, she was senselessly taken from all of us, but her daughters will carry the weight of this traumatic event forever. They lost their mom, who they loved dearly. Please help to make this easier for them by donating whatever you can to support them moving forward." Police continue to investigate.
