Witness recounts attempted intervention in Escondido attack that killed veteran

A witness who tried to intervene outside Army veteran Kerry Sheron's Escondido home describes a confrontation with suspect Thomas Butler, including a doorbell-cam capture of Sheron being punched and kicked; the witness chased Butler away, called 911, and Sheron died four days later after life support. Butler faces murder and related charges, with motive still unclear, and the home had long been decorated with flags and Trump tributes.
