Office of the State's Attorney for Baltimore City

For Immediate Release 5/3/2017

West Baltimore— Former Lockerman-Bundy Elementary School teacher, Mathew Book, was sentenced to 20 years— suspend all but 12 years— in prison for sexually assaulting a student in 2011.

Assistant State’s Attorney Natalie Amato prosecuted the case.

Book was found guilty of one count of the sexual abuse of a minor, one count of third degree sex offense, two counts of fourth degree sex offense, and one count of second degree assault.

Book is a repeat sex offender. In 2014, Book pled guilty to sexual assault charges involving incidents in both Baltimore City and Baltimore County, and he is currently pending federal child pornography charges in Minnesota.

In October of 2011, Book isolated a Lockerman-Bundy Elementary student in the computer lab where he taught and sexually assaulted the student. During a separate incident that same month, Book assaulted the same student when he pulled the student’s bottoms down and rubbed lotion on the child’s buttocks.

According to investigators, faculty noticed an immediate change in the child’s behavior following the attacks. The child, soon thereafter, told a faculty member about the attacks.

“I was struck by how brave the victim was throughout this process,” Assistant State’s Attorney Natalie Amato said. “In cases like these, it is typically very difficult for children to testify against someone who is— or was— in a position of power over them.”

In addition to serving his prison sentence, Book must also register as a sex offender and will remain on the registry for the rest of his life. Amato says she’s been working with federal authorities in Minnesota for approximately a year to ensure that he is extradited to Minnesota to stand trial.

“I applaud this survivor’s strength and resilience, and thank ASA Amato for her dedication to ensure justice was served,” said State’s Attorney Marilyn Mosby. “I hope this conviction and sentence brings closure to this family and supports their road to recovery.”

State’s Attorney Mosby considers this case yet another example of why the Maryland Rules of Evidence need to be brought in line with Federal Rules of Evidence, which allow for the admissibility of prior sexually assaultive behavior in the prosecution of serial child molesters and sexual predators.

“For the past four years, I’ve been in Annapolis fighting to level the judicial playing field with legislation that would give prosecutors and the court the necessary tools to ensure just outcomes in serial sexual assault and serial child molestation cases,” continues State’s Attorney Mosby. “Currently, in federal cases, evidence of a defendant’s similar past sexual assaultive behavior can be introduced in new cases when that same defendant allegedly attacks a new victim. I will continue to fight until this is possible in Maryland courtrooms.”
