A Montgomery County judge ordered a father and daughter charged in a Silver Spring stabbing of a relative to be held without bond Friday, citing concerns for public safety and a lack of verified housing for either defendant.
During separate bond review hearings in Montgomery County District Court in Rockville, District Court Judge Sherri Koch determined that Brittany Dunn, 24, and William Andrew Dunn, 54, posed a danger to the community if released.
The pair are charged with attempted first-degree murder, conspiracy to commit first-degree murder, first-degree assault and second-degree assault in connection with the alleged attack that occurred June 4 in the 3700 block of Stepping Stone Lane in Silver Spring.
According to Montgomery County Fire and Rescue Service (MCFRS) radio transmissions, first responders were dispatched to the area shortly after 5 p.m. for the report of a stabbing. In a radio transmission to Suburban Hospital in Bethesda, an MCFRS crew member said that they were transporting a 67-year-old man who said he had been attacked and choked from behind and then stabbed with a knife. The man suffered a stab wound to the top part of the sternum, according to the radio transmission, and blood was on the knife up to about three inches.

It was a week before officers with the U.S. Marshals Service Capital Area Regional Fugitive Task Force caught up with and arrested the pair in the 14900 block of Broschart Road in Rockville on Thursday.
According to prosecutors, Brittany Dunn told investigators after her arrest that she approached her uncle with a knife but “froze” and did not carry out the stabbing. Prosecutors said she told police that her father then stabbed his brother at the base of the neck.
Assistant State’s Attorneys Peter Larson told the court that the victim suffered a stab wound to the neck after being rendered unconscious and described the allegations as “a gruesome series of events.”
Larson also said investigators expressed concerns about the mental health of both defendants.

Dunn’s public defender Sean Frazzette told the court that Brittany Dunn has no prior criminal record, but could not provide a verified address where she could live if released. Frazzette said Dunn reported she planned to stay with a cousin in Gaithersburg, but the relative told pretrial services that no such arrangements had been made.
Frazzette asked the court to consider home detention, noting that she has no criminal history and arguing that, based on the state’s allegations, she was not the primary actor in the attack.
Koch denied the request.
“In light of the allegations in this case” and the lack of a stable residence, Koch said, “I do find that she is a danger to the community,” ordering Dunn held without bond while leaving open the possibility of a future motion to revise the bond status if housing can be secured.
During William Dunn’s hearing later Friday afternoon, prosecutors alleged that he was the person who rendered the victim unconscious and then stabbed him in the neck.

According to Larson, investigators said Brittany Dunn told police that her father carried out the stabbing after she was unable to do so herself.
Like his daughter, William Dunn has no known criminal history, according to Dunn’s public defender. Officials told the court that Dunn reported he planned to seek housing assistance through the Montgomery County Crisis Center if released, but no residence could be verified.
His attorney argued that the charges remain allegations and noted Dunn’s lack of a criminal record and history of appearing for court proceedings. The defense also asked the court to leave open the possibility of home detention if a suitable address could be identified.
Koch again found that the defendant posed a danger to the community and ordered William Dunn held without bond.
Both defendants are represented by the Office of the Public Defender.
Court records show preliminary hearings for Brittany and William Dunn are scheduled for July 10 in Montgomery County District Court in Rockville.
Following the hearings, Frazzette declined to comment further on the case or on the victim’s current condition.
