KKCO-TV reports that Israel Massingill was sentenced Friday after a jury in March convicted him of first-degree murder, attempted first-degree murder, patronizing a prostituted child and drug possession.
Prosecutors say Massingill shot Kiera B. Quintana to death and attempted to kill another 17-year-old girl.
In handing down the sentence, Judge Gretchen B. Larson noted that Quintana was killed in cold blood.
