Prosecutors said he killed her when she refused to resume their relationship

A Sodus man is headed to prison for killing his ex-girlfriend after emotional testimony at his sentencing Friday.

Twenty-year-old David Knight-Hollis pleaded guilty to second-degree murder charges for the death of 17-year-old Alyssa Taft. Knight-Hollis will serve 20 years to life behind bars after he killed Taft at a home on Boyd Road in Sodus in November.

Last November, prosecutors say Knight-Hollis lured Taft to his home on Boyd Road in Sodus on the pretext of returning money he owed her, then tried to convince her to resume their relationship, which ended in the summer. When she tried to leave, investigators say he stabbed her in the ribs and slit her throat to stop her from screaming.

Taft’s mother Sarah gave passionate testimony in court Friday, excoriating her daughter's confessed killer and sharing her pain about the loss of her child.

She said her daughter was a kind and gentle soul who would help anyone, loved animals, and was all set to pursue her love of geology at SUNY Oswego.

By committing this selfish act of violence, Sarah Taft said, Knight-Hollis had shattered her family. Judge Richard Healy said the lives of Knight-Hollis and his family were also ruined.

Knight-Hollis declined an opportunity to speak and said very little except that he accepted his guilty plea and the consequences.

“Really, the only thing he could do at this point was to accept responsibility for what he did," Andrew Correia, Knight-Hollis' public defender, said. "Privately he showed extensive remorse."

The district attorney says he spoke with the victim's family before making any plea deal and they all agreed it was better than going through a trial.

"I did not want to go through a trial on this," Sarah Taft said. "He got a close enough sentence."
