If I recall correctly, it has been about 6 months since the incident took place and law enforcement agencies have released very little info.
Floorboards in the hours were ripped up, but they never stated why they did it. An autopsy was performed but the results were never released (as far as I knot), and the only major comment was that the son was a "person of interest".
Have there been any updates that I missed or does it really seem like the police have essentially said nothing?
