ARAPAHOE COUNTY, Colo. — A former teacher’s aide will spend 18 years in prison for second degree murder after pleading guilty in a drug overdose case.

Almeda Sullivan was dealing pain killers out of her home in Centennial. She provided some to 21-year-old Carter Higdon who died of an overdose.

In court, Sullivan apologized for what she did before she was taken away to begin her sentence. Prosecutors said she was well aware of the risks of dealing drugs. “…She became a merchant of death,” Arapahoe County District Attorney George Brauchler said.

Sullivan was the first drug dealer in Colorado to be charged with murder in a drug overdose case.
