The body of our boss was found at 9 am. she could have been killed in the evening. The killer could have left the cigarette, but I think it was Anna who smoked it.The phone was also broken by Anna,She could get bad news and get very angry. The torn photo also indicates that Anna must have had a fight with her husband. They could buy tickets to Bali a long time ago and were preparing to fly, but Anna found out something terrible. The wallet can be both Anna and her husband, there would be more details. The wine was definitely drunk by Anna from sadness. My conclusion is this. Anna found out about her husband's infidelity, tore up the photo, broke the phone and drank some wine. The husband came to explain everything to her, but she attacked him because she was already drunk.Her husband, in self-defense, hit her with something and left, fearing punishment.
