From your link:
Investigators believe William Sublett, 57, was beaten to death.
His wife and several friends said the father of 11 was the most dedicated family man you could meet.
His friends also said Sublett was an active member at Healing Place Church in Baton Rouge. They added he was actually a part of a medical mission trip to Africa earlier this year.

This is horrible. I live just outside of BR and know of the Healing Place Church.
Seems like he was a wonderful man.
I hope this is solved soon and his family gets some answers.
