The man accused of murdering Morgan Freeman's step-granddaughter E'Dena Hines has claimed that she was having an inappropriate sexual relationship with Freeman before her death.
Lamar Davenport says that Hines told him she was having an affair with Freeman. According to the New York Daily News, Davenport's lawyers said: "E'Dena Hines disclosed to Lamar Davenport and others that her grandfather engaged in a sexually inappropriate relationship with her,"
Therapists also testified at the New York court that Davenport had admitted that discussion of an affair between Freeman and Hines had caused several of their arguments.
Dr Jeremy Colley testified that many of the disputes that the couple had were about the subject of infidelity. He told the court: "Lamar admitted to me that they had a violent relationship. Their disagreements could be emotionally intense."
Davenport stands accused of stabbing Hines multiple times in her torso in the street outside their Manhattan home in 2015.
Lamar Davenport pleaded not guilty to her murder by reason of insanity.
This isn't the first time that it has been suggested there was an inappropriate relationship between Freeman and his step-granddaughter Hines, who was the daughter of an adopted child of Freeman and his first wife Jeanette Bradshaw, Deena Adair.
Back in 2012 there were rumours that the pair were to marry. However, both parties moved quickly to dispel those rumours.
Freeman released a statement to US Entertainment website TMZ that said: "The recent reports of any pending marriage or romantic relationship of me to anyone are defamatory fabrications from the tabloid media designed to sell papers.
"What is even more alarming is that these fabrications are now being picked up by the legitimate press as well,"
E'Dena also released a statement at the time that said: "These stories about me and my grandfather are not only untrue, they are also hurtful to me and my family."
The American actor and Hines are not related by blood.
The court heard testimony last week from a witness who claimed she saw Davenport stab Ms Hines 25 times.
Davenport's defence argues that he was under the influence of drugs and not in his right mind at the time of the incident.
Colley continued: "Mr. Davenport did not possess the intent to kill Ms. Hines.
"My opinion was that he lacked substantial capacity to appreciate the wrongfulness of his actions and know the nature and consequences of his conduct."
If found guilty of second degree murder he faces 25 years to life in prison.
