Swiss police say the man who attacked passengers aboard a train with a knife and burning liquid, killing one and wounding five others, has died of his own injuries.

St. Gallen canton (state) police said the suspect, described only as a 27-year-old Swiss man from a neighboring state, had been suffering from serious burns himself. They said in a statement that he died in a hospital Sunday.

A 34-year-old woman earlier died of her train attack wounds in a hospital. Three others remain in critical condition.

A 34-year-old woman died Sunday from wounds suffered after a man attacked her and four others with a knife and a burning liquid aboard a crowded train in Switzerland.

Police are still searching for a motive but said there's no indication the suspect, identified only as a 27-year-old Swiss man from a neighboring region, had ties to extremist groups.

The suspect and three others, including a 6-year-old child, remained in critical condition Sunday with life-threatening wounds, St. Gallen canton (state) police spokesman Hans-Peter Kruesi told The Associated Press.

Swiss police searched his home after the Saturday afternoon attack on the train as it neared the station in Salez, close to the Liechtenstein border. Kruesi would not comment on what evidence was seized at the home in a neighboring canton, but said "so far there are no indications this was a terrorist or politically motivated crime."
