Police issued an arrest warrant for a Massachusetts woman in connection with the death of her police officer husband earlier this week.

Authorities are searching for Karen Solomon, the co-founder of a group that advocates for the mental health of police officers, after Worcester police officer Kurt Solomon was found dead at the home they owned together on Tuesday.

Worcester Police Chief Paul Saucier said at a news conference on Friday that the arrest warrant charges Karen Solomon with assault and battery with a dangerous weapon with serious bodily injury. She is considered armed and dangerous, the chief said, though Kurt Solomon’s service weapon was not missing from the home.

Saucier said Solomon’s injury involved a sharp object but declined to provide further details, citing the ongoing investigation into the officer’s death.

Karen and Kurt Solomon shared a home and had been married, court records indicated, but authorities declined to discuss their current relationship, citing domestic violence privacy rules, according to The Associated Press.
