My understanding is they are still undertaking computer and cellphone analysis and they wouldn't release this "sensitive information" until then. They haven't released toxicology reports to the public. Also this quote came from the recent article.
Police released the sensitive information after they learned that some of that sensitive information was released by the family. It was out of respect for the family that it was withheld, but if family was not concerned with confidentiality of details that may indicate suicide, then police don't need to withhold that sensitive information anymore.
The "sensitive info" comment is from Feb 25.
