WORCESTER, Mass. (AP) — An arrest warrant has been issued for a mental health advocate who remained missing Saturday, more than four days after police found the Massachusetts officer she had been married to dead in their home.

Karen Solomon, 58, was last spotted in a doorbell camera video, walking down a street in a T-shirt, shorts and flip-flops early Tuesday morning, just minutes after Worcester police officers responded to a call from the home where Kurt Solomon was found dead.
