My dad was actually at the Gurudwara when this happened...
There was a field hockey tournament going on, and most of the competitors were Punjabi; field hockey is a lot bigger in socal in fact I think a few of the KJ boys were up north too.
From what dad ji said, one guy pumped bullets into another guys stomach and shot a few rounds, and then started to run (apparently dad was unaware of the second gunman) then he dropped his keys and the gun and the sangat ran after him and beat the daylights out of him till the police came.
They set up a perimiter with no ins-and-outs until they got individuals' information.
As I understand it, one of the suspects is the son of Balbir Dhami

And for those who are familiar with Sac, this was at Bradshaw gurdwara...
