Former U.S. intel director’s daughter sentenced to 35 years in prison for murder after retrial

ROCKVILLE, Md. (TCN) -- In a retrial after her 2023 conviction was overturned, the daughter of former U.S. intelligence director John Negroponte has again been sentenced to 35 years in prison for murder.

Sophia Negroponte, 33, was convicted of second-degree murder in January 2023 for fatally stabbing Yousuf Rassmussen, 24, in February 2020. According to NBC Washington, the two bonded over having been adopted into successful families. Their relationship was described as platonic.

Negroponte reportedly had a history of violent outbursts, particularly when she had been drinking, and she attacked Rasmussen with a knife when he returned to her home to retrieve his phone, according to NBC Washington. Prosecutors called her a ”powder keg ready to go off.”

On March 31, 2023, she was sentenced to 35 years in prison, as previously reported. 

According to The Associated Press, an appeals court threw out the murder conviction in January 2024 because the jury had been allowed to listen to a police interrogation of Negroponte, which had been contested, in addition to witness testimony from the prosecution that questioned her credibility.

The AP reported at the time that three judges with Maryland’s Appellate Court sent the case back to Montgomery County Circuit Court for a new trial. They said, “The detectives commented that they found (Negroponte’s) version of events ‘hard to believe’ and that it looked like appellant was not being honest. Under our long-established precedent, these kinds of assertions are not relevant and bear a high risk of prejudice.”

In November 2025, a jury found Negroponte guilty of second-degree murder, and she was sentenced March 6 to 35 years in prison, according to the AP.

According to NBC Washington, Montgomery County State’s Attorney John McCarthy said the sentence mirrors the one imposed following Negroponte’s first trial. He said, “This is an appropriate and just outcome in light of the seriousness of this crime and the consistent findings of two separate juries who carefully evaluated the evidence.”

Negroponte’s father was appointed the nation’s first intelligence director by then-president George W. Bush in 2005, according to the AP. He later served as deputy secretary of state and as an ambassador to Iraq, the Philippines, Mexico, and the United Nations.
