Police Chief Jason Ziegler declined to say whether all four victims were targeted.
Police declined to release details of the 911 call that alerted authorities to the slayings. The Associated Press and other media outlets asked for audio and a transcript of the call, but police denied the requests, citing a provision of the state's open records law that allows authorities to withhold such information during an active investigation.

Hmmm... make sense to withhold during an investigation - especially if there's something they really do not want the public to be aware of right now.
