A woman in her 50s, identified as A, has been arrested on suspicion of murdering her husband B, a famous real estate instructor, by hitting him on the head with a glass jar. Initially, the death was considered accidental during a marital dispute, but police investigation revealed that A suddenly attacked B while he was lying down, leading to charges being upgraded from involuntary manslaughter to murder. Although A denies the allegations, the court issued an arrest warrant due to concerns over evidence destruction and possible flight. Police plan to conduct further investigation into the detailed circumstances with A.
