The victim was fatally stabbed onboard a train near the Hollywood and Vine Station, under the W Hotel on Hollywood Boulevard.
According to the Los Angeles County Sheriff's Department a Hispanic man was stabbed by another passenger while riding the Red Line train at about 8:20 p.m. Friday. The train was heading northbound toward the Hollywood and Vine Station.
Sheriff's officials said the victim and the suspect got into an altercation on the train. The victim took out a plastic chain and began swinging it at the suspect.
The suspect, described as an Asian man in his 20s, reportedly hit the victim in the head with a skateboard, then pulled out a knife and stabbed the victim in the upper torso. The victim was declared dead at the scene.
The victim was identified as 59-year-old North Hollywood resident Jesse Garay.
There were many passengers on the train who witnessed the bloody event.
"The guy who was bleeding, ultimately, he pulled out like a chain, and he's like wanting to hit this guy, and that guy is kind of blocking with a skateboard," said witness Mark Aucoin, who said he felt the victim was very intent on hitting the suspect with the chain.
Witnesses described the suspect as very distraught after the stabbing. He reportedly fled the scene carrying two skateboards. He was described as having acne scars on his face.
Deputies said surveillance footage shows the suspect clearly, and they believe the suspect is a regular on the train.
