A jury on Tuesday convicted Philip Chism, a Massachusetts teen accused of raping and murdering a math teacher at his school in 2013, on the aforementioned charges after nine hours of deliberations.
Chism, who was 14 at the time, followed his teacher, Colleen Ritzer, into a school bathroom where he strangled her, stabbed her at least 16 times, and then raped her, according to Fox News.
Now 16, Chism was convicted of rape but acquitted of a second rape committed with a tree branch in woods near the school where Chism carted her body using a recycling bin. He was also convicted of armed robbery for stealing Ritzer's belongings, including her underwear.
By finding him guilty, the jury rejected the insanity defense put forward by Chism's attorneys which alleges that he was suffering from a psychotic episode at the time of the incident and thus not criminally responsible for his actions, according to Reuters.
Ritzer's family was somber after the ruling, noting that it wouldn't bring their daughter true justice.
"This guilty verdict, while the beginning of justice for Colleen, is certainly no cause for celebration, because there can never be true justice for the crime committed," said her father, Tom Ritzer.
Now that he's been found guilty, Chism faces three possible life sentences, reported WBUR. However, due to rulings made by the U.S. Supreme Court and the highest court in Massachusetts, it would be possible for Chism, as a juvenile, to become eligible for parole after 15 to 25 years into his sentence.
The time of his sentencing is still unknown, and the earliest it can come is in January.
