I think something is up.
The ISP issued an arrest warrant on a felony weapons charge. DP went to the police station, paid the bail bond of $7500 (check written by his son, Stephen), and was released.
Tomorrow there's a hearing on the disposition of DP's guns. The hearing was supposed to be Thursday morning, but the judge has pushed the hearing back to Thursday afternoon. It was expected that the guns would go to DP's son, Stephen, but in light of today's arrest on a weapons violation, I doubt those weapons will be released to anyone.
Tomorrow is also the hearing in the Savio estate, and DP and his two oldest sons, children of KS, are to attend, along with Savio relatives.
There's a rumor that the two Peterson boys, Kristopher and Tom, will be appearing before the grand jury next Thursday, May 29th. It's also rumored that next Thursday will be the last day of hearings in this case.
I could be way off base on this, but it seems to appear that the PTB are getting all their ducks in a row. If the grand jury were to hand down an indictment in the coming weeks, and an arrest is to be made, the ISP doesn't want DP to be armed or have access to weapons, when they arrest him.
