Fullerton CA. Cops were called by one of 2 young kids in a house (they're safe). Found dead - 2 adult males and one female (mother, stepfather, and a friend of the family). Neighbors reported gunshots.
3 were arrested a day later. Males age 25 and 21 and a 17 yo female. All were charged with murder. All were furries.
Before the cops announced arrests, Twitter had a call out to find the missing teenager. She had some relationship with the 25yo. She is daughter of the deceased mom, who was a furry too. Mom and daughter went to meets together.
Attention goes to the 25yo. He had numerous online accounts with some recent ranting about relationship trouble, a recent photo of a gun magazine, and a mention of psychiatric drugs. There was even a supposed screenshot being heavily shared of a Facebook chat where he admitted planning murder to someone else. The 21yo seems to have military affiliation and the 17yo was rumored to be unstable.
EDIT - removing links. It's a horrible story not on the gossip level. Let regular reporters and the cops process it.
