The 2025 Taylor’s University pet-killing and stabbing case refers to an incident on 14 July 2025 in which 22-year-old Chinese national student **You Wei (游伟)** allegedly killed his ex-girlfriend’s pets—using insecticide—then went to Taylor’s University in Subang Jaya, Malaysia, and slashed her neck multiple times, resulting in grievous injury. The victim, **Wu Jalin (吴嘉琳)**, survived and was hospitalized in stable condition.

Psychological profile and online activity

Sources describe **You Wei** as exhibiting increasingly controlling and emotionally volatile behaviour. Reports indicate he had resentment over the breakup and had previously barred the victim from leaving home.

While detailed mental health evaluations have not been released, experts highlight that such obsessive and aggressive control—especially where animal cruelty precedes interpersonal violence—is often a marker of serious psychological instability.

A prolific history of animal cruelty

Evidence points to a disturbing pattern:

• Chat screenshots and social media posts circulated in Chinese-language forums show **You Wei** had used insecticide or disinfectant to harm or kill the victim’s pets—specifically at least one cat and a hamster.
• A witness reportedly stated: “He sprayed the cat with bug spray. I think it really died.” Videos purportedly show a man dousing a cat’s face with pesticide until it lay motionless.
• Additional social media claims include that **You Wei** used insecticide to kill both a cat and hamster after the breakup, and the victim’s mother allegedly posted a screenshot claiming he “killed her kitten” as a form of intimidation.

This cruel treatment of animals is widely recognized as a red flag for potential violence toward humans. Studies show individuals who harm animals are significantly more likely to escalate to interpersonal violence.

Systemic failures and pathway to the attack

There are no public records of prior criminal charges or interventions regarding **You Wei**’s behavior—neither from authorities nor from university administration.

Consequently, the animal cruelty acts went unchecked, and it appears there were no warnings or red flags acted upon before the stabbing. This failure to recognize and intervene may have contributed to the escalation.

The attack and legal outcome

On **14 July 2025**, **You Wei** allegedly entered Taylor’s University and slashed his ex-girlfriend, **Wu Jalin (吴嘉琳)**, in the neck. Bystanders detained him until authorities arrived. The victim sustained a serious but non-fatal neck injury and was treated and stabilized in hospital.

He was charged under **Section 326** of the Malaysian Penal Code (causing grievous hurt with a dangerous weapon), which carries a penalty of up to **20 years’ imprisonment**, possibly with flogging or a fine.

The case received extensive media and public attention in both English- and Chinese-language outlets, highlighting the clear link between animal cruelty and human-directed violence, and calling for better prevention systems.
