Fatality on Mt. Sill

(taken from the Inyo County Sheriff's Office Facebook post):

MT. SILL (PALISADES), CA. October 22, 2019 – On October 20 (late afternoon), two hikers/mountaineers were descending the L-shaped snowfield below Mt. Sill when one slipped and tumbled approximately 300-400 feet sustaining unknown but serious injuries. His partner notified the Inyo County Sheriff’s Office through the use of a satellite communication device.
Due to the location and seriousness of the reported injuries, aerial support was requested. Sadly, the patient succumbed to his injuries prior to the arrival of the helicopter. CHP Inland Division Air Operations made an attempt to hoist the fall victim that night but was unable to land due to the high elevation (~13,200'), and gusty north winds.
On October 21, at noon, six Inyo Search and Rescue team members were inserted about 100 feet below the location via Chinook. Team members hoisted the deceased from his location around 2:30pm, and returned to the Bishop Airport where custody was transferred to the Inyo County Coroner.

Does anyone have any details? I wonder if they had an axe, traction, helmets...?

Very sad. Always hard to lose a member of the tribe. My condolences to the deceased’s friends and family.

Looks like a good guy. Any details? Condolences.

It’s terrible no matter what the age, but these deaths of young people are a stab in the heart. 

His brother posted on that fb page saying they had training and proper equipment.

I'm not familiar with this specific route but my partner and I climbed the engram couloir on Mt Gilbert on the same day (Sunday). The snow was frozen solid (more like ice than snow), and didn't warm up at all throughout the day given slope aspect and daytime temps. I'm not sure what the slope angle of this snowfield is but any slip and there was likely no chance of self arrest given the conditions. Very unfortunate - RIP

Just posting to say, hope his partner and family can find peace ---

be well

Was it on the descent route to the glacier ?

The OP said it was on the L-shaped snowfield, so, yes, on the descent to the glacier.
