TAIPEI (Taiwan News) — Two sisters were killed in New Taipei after being struck by a car and stabbed multiple times by the driver on Monday at 11 a.m.

The assailant, a 46-year-old male surnamed Hsieh (謝), was married to the elder sister and had a history of domestic abuse. Both victims had heavy blood loss as they soon lost vital signs and died, per CT Want.

Following the attack, Hsieh fled in his car. A manhunt soon ensued, with Hsieh later surrendering at 1:25 p.m. at a police precinct in Shengang, Changhua.

He has since been brought back to New Taipei, where he awaits questioning. He turned himself in after discovering he was being followed by police, also claiming mental illness as a reason behind the attack.

The double homicide occurred in New Taipei's Tucheng District, Mingde Road, Section 2. The incident shocked many bystanders who were powerless to protect the two sisters.

Media reported that Hsieh is unemployed and was involved in a domestic dispute leading to an emergency restraining order on June 25. The two were married for 11 years and have two daughters.

Reports said he was angered by an inability to see or care for his daughters, leading him to seek revenge by stalking his wife and sister and killing them when they left their residence on a scooter.
