The day after that newsletter article (Feb 5) you link was posted, ABC news (Feb 6, which I linked) contacted the Sheriff's office and they stated they have not named any suspects.From post # 437 and the link in this thread :
Community wants answers in murder case
According to the Mohave County Sheriff’s office, they are suspects in the case.
This is from the sheriff's office and is not considered to be only his own opinion ; at least according to the LE press release in said article.
Hope that helps.
It's sad that it's nearly four years and still no answers.
MOO.
Ie they flatly contradicted the claims made by the writer of that article.
