9:22 AM: A Seattle Fire “assault with weapons” response is arriving at 6th SW and SW Cambridge, on the edge of Westcrest Park (map). According to radio transmissions, a man believed to be in his mid-20s has multiple stab wounds. Police are searching. We’re on the way to find out more.

9:29 AM: Life-threatening injuries, according to medics’ radio discussion, which also says the man was found “on the street,” no weapon found, circumstances unknown.

9:37 AM: Our crew has arrived and says that roads around the scene are being closed off as the search continues.

9:45 AM: You may see a helicopter searching the area too. Meantime, early details have been published to SPD Blotter, including:

… Just before 9:15 AM, the victim, a man in 20’s, walked out of the woods and collapsed on a sidewalk near 6th Avenue SW and SW Cambridge Street. The man said he’d been stabbed and passersby called 911.

9:51 AM: Our crew confirms Guardian One is over the area. We’ve also spoken with a lieutenant who confirms what’s been reported previously and says that Homicide Unit detectives have been sent.

10:38 AM: No new information yet, but the investigation continues. If you have any information, call 911.

4:54 PM: Police have just provided an update – saying that the victim has died, and that he was a teenager, 15 years old, not an adult as originally believed:

The victim has died from his injuries. Detectives have confirmed he is 15 years old, not in his 20’s as previously reported. This crime occurred at the southern portion of Westcrest Park. Police are investigating and are asking anyone with information about this case to call 206-233-5000.

We just talked with SPD spokesperson Det. Mark Jamieson and he confirmed that’s all the new information they have – they want to hear from anyone who might have seen or heard anything that can help with this “very active homicide investigation.” This is the third homicide investigation this year in West Seattle – the first one was the May shooting on Alki that killed a 23-year-old man (still no arrests); the second one was the baseball-bat killing of a 24-year-old man at an encampment over Highway 509 in June (two people arrested and charged).

WEDNESDAY NOTE: We have published an update on the case here.
