Sixty-five dead or dying seals were found bludgeoned on a beach in eastern P.E.I. (Name withheld on request)

More details are emerging about the bludgeoning of seals in eastern P.E.I. in January, including the fact that, of the three teenagers involved in the incident, the youngest came up with the idea and did most of the killing.

The three boys, ages 15, 17 and 18, who all pleaded guilty to animal cruelty charges, were in Georgetown provincial court Thursday for sentencing in the case.

They were supported by some of their family members.

Although Judge Nancy Orr deferred sentencing to June 13, several new facts were read in court.

According to an agreed statement of facts, 49 of the 65 seals that were found bloodied, dead or dying on a shore near Beach Point on Jan. 26 were seal pups.

The boys used what Crown attorney Lisa Goulden described as a club, hockey stick and a metal tool for harvesting clams called a clam hack, to bludgeon the seals.

Afterward, one of the teens burned the hockey stick.

The court heard the teens were remorseful and cooperative with fishery officials and police officers who caught up with them in the days that followed.

Goulden argued jail is an option, but so is house arrest, probation and community service.

One of the teens' defence lawyers, Brenda Picard, called the incident "stupid, senseless and illegal" and said the boys take full responsibility.

Orr ordered a two-year weapons prohibition for the 15-year-old starting immediately.

She'll deliver the rest of their sentences June 13.
