One of Coll’s lawyers, Sam Schmidt, declined to comment after the hearing.
Kelly described Spear as a “second father,” while Donna Spear said he had helped raise her own children.
“We are extremely satisfied with the sentencing,” Kelly told reporters after the hearing.
Coll was arrested in June 2015, nearly a year after the city agreed to a $2.75 million settlement with Spear’s family.
Coll’s lawyers argued during his trial that prosecutors could not prove the kicking killed Spear, who suffered from severe medical problems.
Prosecutors said that in December 2012, Spear, who suffered from end-stage kidney disease, asked to see a doctor but was stopped by Coll, who said the doctor was not available.
According to testimony at the trial, that started a fight that ended with two other officers restraining Spear on the ground while Coll kicked him repeatedly in the head. Spear was pronounced dead soon after that.
Jurors found that Coll worked with the two other officers, Brian Taylor and Anthony Torres, to cover up the assault, falsely claiming that Spear attacked Coll with a cane. Both Taylor and Torres pleaded guilty to charges stemming from the cover-up, and Torres testified against Coll.
