2010年4月，內蒙古平庄鎮某小區內發生一起震驚社區的命案。事發單位是302號房，鄰居們在連續數日察覺異味後，向物業管理部門反映。物業工作人員在報警並獲得派出所同意後，打開房門，隨即被強烈的屍臭味撲面而來。警方與法醫趕到現場後，發現屋內有三具懸掛於天花板的屍體，分別為房屋男主人、其兒子以及兒媳。由於當時氣溫已漸升高，屍體已有明顯腐敗跡象。

法醫檢驗後確認，三人的死亡時間大約在一週之前，且遺體上存在遭受侵害與虐待的痕跡，案情因而更顯詭異。警方初步調查時，發現這個家庭本有四口人，唯一倖存並未出現在現場的是女主人張婷。

警方進一步調取小區監控，發現案發後的一週內，張婷曾多次出入事發住處，但每次僅停留短暫時間，並常帶著袋子離開，卻未曾向警方報案，舉止異常。警方據此懷疑她與案件有重大關聯。

經過布控與蹲守，警方於次日成功將張婷抓捕。張婷被帶回審訊後，情緒失控並供述部分案情。原來婆婆是雙性人，強暴兒媳後讓她懷孕，兒子事後知道失控，最終男主人、其兒子以及兒媳均被張庭殺害。

這起案件因為涉及家庭成員之間的極端矛盾與犯罪，震動當地社會，許多居民難以置信，一個普通社區竟會發生如此駭人聽聞的事件。輿論普遍呼籲，要加強對家庭矛盾與心理問題的干預機制，避免類似悲劇重演。

In April 2010, a shocking homicide case emerged in Pingzhuang Town, Inner Mongolia. Residents of a residential complex had repeatedly complained about a foul odor coming from apartment 302. When property management staff, accompanied by police officers, entered the apartment after receiving no response at the door, they were overwhelmed by a strong stench. Inside, they discovered three bodies hanging from the ceiling.

The deceased were identified as the male homeowner, his son, and his daughter-in-law. Forensic examinations suggested that they had been dead for about a week, and the remains showed evidence of abuse before death. The grisly discovery left local authorities and residents deeply unsettled.

Investigators soon realized that the family was originally a household of four. The only missing member was the female homeowner, surnamed Zhang. Security camera footage revealed that Zhang had been visiting the apartment intermittently in the days after the suspected time of death, usually staying for only short periods and carrying bags away each time. Crucially, she never reported the deaths to authorities.

This unusual behavior raised suspicions that she might have been directly involved in the crime. Police set up surveillance and, the following day, apprehended Zhang when she returned to the building. During interrogation, she broke down emotionally and admitted partial responsibility, confirming her role as the prime suspect.

The case, which involved severe family conflict and shocking violence, drew widespread public attention. Authorities have kept many details confidential due to the disturbing nature of the events, and the case was forwarded for further judicial proceedings.

Local communities expressed disbelief that such an atrocity could occur in an ordinary residential block, and the tragedy sparked renewed calls for better mechanisms to address domestic conflict and mental health issues in order to prevent similar incidents.
