A Newark man has pled guilty in the 2024 Murder of Tracy Nyariki.
On April 29, 2026, Nobert Matara, 33, pled guilty to Murder 1st Degree in New Castle County Superior Court. The plea follows an investigation into the December 2024 murder of 33-year-old Tracy Nyariki.
"The facts of this case are beyond disturbing," said Attorney General Kathy Jennings. "It is difficult to comprehend this kind of violence. I am deeply grateful to our team and to the New Castle County Police who have worked tirelessly to achieve justice for the victim and her family. May it bring them some measure of peace."
"I'm thankful for the hard work of our officers and detectives at the New Castle County Police Department, along with everyone at the Delaware Department of Justice, who carefully investigated this horrific incident," said New Castle County Police Chief Col. James J. Leonard III. "Their commitment to justice and attention to detail were instrumental in securing this plea agreement."
On December 17, 2024, Nobert Matara lay in wait at the Newark home of his ex-girlfriend, Tracy Nyariki. When she arrived a few hours later, he attacked her, stabbing her 58 times, dismembering her, and placing her body in a suitcase. He then fled to Aberdeen, Maryland where he was found at a motel with Tracy's body in the trunk of his car.
Matara will be sentenced at a date to be determined and faces a mandatory life sentence.
