A 21-year-old, who gave a lethal overdose MDMA to 91原创 teen Carson Crimeni, will spend 18 months behind bars, a judge ruled today.

The young man, who cannot be named because he was 17 when Carson died, will spend 18 months in a provincial prison followed by 18 months on a supervised release.

Carson was 14 when he died in a Walnut Grove park from a massive drug overdose.

Following Thursday morning鈥檚 decision, Carson鈥檚 father Aron Crimeni spoke with reporters outside the New Westminster Supreme Court, expressing his disappointment with the sentence.

鈥淲e were hoping for at least two years of incarceration鈥� 18 months, it seems very insufficient for the crime,鈥� Dad said, adding he hoped a longer sentence could set a precedent.

The offender pleaded guilty and admitted to selling a dose of MDMA to Carson at a local skate park on Aug. 7, 2019. When Carson asked for a second dose some time later, the offender gave him a much larger dose than Carson requested.

Carson believed he had ingested the equivalent of three 鈥渃aps鈥� of MDMA, or about 0.3 grams. In fact, he may have received as much as 13 caps in total that day. An autopsy revealed blood-test results consistent with having consumed at least 10 times a single average dose.

A lengthy police investigation led to manslaughter charges last year.

As the trial date approached, the accused entered the guilty plea.

Crown prosecutors asked Justice Kathleen Ker to impose a two-year jail term, to be served in adult provincial prison, with a year of supervised release. Defence lawyers asked the judge for 12 to 18 months in prison and the remainder on release.

Ker said the offender鈥檚 moral blameworthiness was 鈥渜uite high,鈥� but believes that he is on the road to rehabilitation with his job, family support, and being off drugs since Carson鈥檚 death.

鈥淗e made a dangerous and stupid decision, and it cost a child his life,鈥� Ker told the courtroom.

鈥淭he raw pain, anguish, and sorrow Carson鈥檚 family has expressed with regard to his needless death leaps off the pages of their victim impact statements,鈥� she added.

Aron, and Carson鈥檚 grandfather Darrel Crimeni, attended the sentencing hearing Thursday. Several officers involved with the case were also present to witness the outcome.
