The boyfriend of Morgan Freeman's late granddaughter has been sentenced to 20 years in state prison for her death. 

Lamar Davenport, 33, was sentenced Thursday for fatally stabbing E’Dena Hines 25 times outside her New York apartment in August 2015, Manhattan District Attorney Cyrus R. Vance Jr. announced in a press release. Prosecutors say Davenport was "under the influence of alcohol (and) drugs" during the crime. 

Hines, who is the granddaughter of Freeman's first wife, was 33 at the time of her death. 

"Ambitious and driven, E’Dena Hines was deeply loved by family and friends before her life was brought to a horrific and tragic end by her boyfriend, Lamar Davenport," Vance said. He described her slaying as an "extraordinarily violent crime."

On Aug.16, 2015, authorities responded to a 911 call at about 3 a.m. They found Hines lying in the street in front of her apartment on West 162nd Street.

Hines had dozens of stab wounds to the chest and was later pronounced dead at Harlem Hospital.

"The world will never know her artistry and talent, and how much she had to offer," Freeman said in a statement to USA TODAY after her death. "Her friends and family were fortunate enough to have known what she meant as a person. Her star will continue to shine bright in our hearts, thoughts and prayers. May she rest in peace."

Davenport was convicted of first-degree manslaughter in May 2018. In addition to his sentence, he faces five years of post-release supervision.
