A 14-year-old boy has been arrested for the murder of math teacher, Colleen Ritzer, in Danvers, Mass.
All seven schools in the Boston suburb were closed as a result of the investigation.
The 24-year-old women's body was found in the woods outside of Danvers High School, early Wednesday morning, Essex District Attorney Jonathan Blodgett told reporters during a news conference.
"We have no reason to believe that any other suspects are involved," Blodgett said.
Ritzer's body was reported missing Tuesday evening when she didn't return home from school. Blood found in the second floor school bathroom helped investigators locate the victim's body.
The boy charged for the murder was found Wednesday at midnight walking along a freeway in the neighboring town of Topsfield, after he was reported missing, having not returned home from school.
The boy's name has not been released on account of his age. He is expected to be arraigned in a closed juvenile court session, CNN reports.
Blodgett did not release any details on how Ritzer died or whether or not she knew her alleged perpetrator.
"She was a very, very respected, loved teacher," Blodgett said of the teacher.
Ritzer's former mentor and co-worker, Joe Spanos, told Fox News that Ritzer had been an example to the community and the kind of woman you hoped your daughters would emulate.
"She was beautiful on the inside and out," Spanos said. "She's not a fighter. She probably never saw it coming."
