- Colleen Ritzer "always wanted to be a teacher," an aunt says

- Ritzer's social network postings offer insight into her personality and passions
(CNN) -- Colleen Ritzer was the kind of high school teacher who made geometry and algebra classes fun. Just a few years older than her students, she used Twitter to send homework assignments and inspirational messages.
Her Twitter profile description read: "Math teacher often too excited about the topics I'm teaching."
Ritzer's lifeless body was found in woods near Danvers High School early Wednesday morning. Prosecutors in Massachusetts charged Philip Chism, 14, with beating the 24-year-old teacher to death.
Investigators did not immediately reveal what connection, if any, Ritzer had with Chism, other than he was a freshman student in the school where she had been a teacher since last year.
Ritzer was "a dynamic and brilliant ray of light," the school district's statement said. "Colleen Ritzer was everything one could ask for in a teacher -- dedicated, passionate and invested in her students. Our entire community will feel this loss for many years to come."
An uncle spoke to CNN TV affiliate WCVB. "She was just a young caring girl who had whole world ahead of her," Peter Martellucci said.
