crashed into the Hongshan reservoir leaving 21 dead and 15 injured [1]. The sudden acceleration towards the lake was a deliberate crime where driver Zhang Mogang was solely responsible [2]. The police investigation ascertained major 4D motives—Divorce, Dissatisfaction of life, Demolition of the house, and Drinking—of Zhang for committing a notorious crime [3]. 
Following his divorce, the 52-year-old rented a state-owned house, which was included in a renovation program. The program: “Regulations on Expropriation and Compensation of Houses on State-owned Land,” outlined in 2016, compensated Zhang 72,542.94 Chinese Yuan for displacement in June; though, Zhang denied receiving it. On July 7, 2020, 8:30 in the morning, he discovered his house was to be demolished; he had nowhere else to live. The divorce, demolition, and impending homelessness brought extreme dissatisfaction for Zhang. Before the rampage, Zhang bought alcohol, consuming it at work. These antecedents’ culmination ensued tragedy.
Pseudocommando & Homicide-Suicide Theory 
The rampage can be classified as pseudocommando and homicide-suicide, Zhang intended to kill indiscriminately during the daytime, publicly with no escape plan. A pseudocommando usually plans for a while and executes the operation driven by strong resentment feelings [4]. Despite the crash’s impulsive nature, prior to that, per the police, it was evident Zhang had a dissatisfied life—potentially indicative of adjuvant planning. Moreover, this incident coincides with consortial-possessive and adversarial homicide-suicide patterns [5]. The intolerable powerlessness feelings, a fragile ego, and a destructive personality leads to one’s annihilation of themselves and others—like what occurred with Zhang [6]. 
Psycho-Social Theory 
The perpetrator of self-generated rampage has predisposed commonalities, like, low social capital, a dissatisfied family life, and an impaired psyche, leading them to becoming an avenger with a pariah self-image [7]. The sudden environmental loss triggered Zhang’s violence and readied him into pursuing a slaughterous act. Here, suicide was not an underlying motivation since he only wanted to keep the situation’s scar everlasting. 
Drinking to Homicide-Suicide 
Alcohol abuse is strongly connected with impaired cognition and judgment which can lead to extreme homicide-suicide cases [8]. Drinking may be a significant catalyst for Zhang’s devastation. Alcohol’s intoxication, dependence, and biochemical effects often lead to destruction [9]. 
Currently, no specific policies stop these incidents from repeating. Though, there are commonalities in their basic causes and execution patterns that can be utilized in future prevention. Community education may be a step in stopping these incidents before they claim more lives.
