Having had a couple of days to digest the information, I think this was one hearsay comment that Clayton Stamper may have gotten wrong.
In full context, we know that Stines was said to be calm and only concerned about being treated fairly when he was actually seen by Stamper following the shooting. It doesn't follow that if Stines believed his wife and child were the targets of a kidnapping that he would have stopped with Mullins, or been calm after the shooting! IMO, I think the hearsay reference was probably more likely something to the effect that Stines thought he was losing his wife and kid and not that this involved a "kidnapping."
Reportedly, Stines had not been acting his normal self weeks prior to the shooting, and told a local reporter he was not commenting on the Sheriffs FB page out of fear of negative posts. Also said he'd lost a considerable amount of weight in a short period and couldn't explain why. These all seem to me to be hallmarks of extreme stress and paranoia-- which could also be making him difficult to live with. Today, I'm more curious than ever whether or not there had been recent talk of a separation or divorce.
As one of his closest and best friends, I can see a situation where Stines family would have confided in Judge Mullins that things were not right with Mickey at home, and changes were about to happen. A paranoid Stines could have believed if Mullins was aiding in the legal separation of his wife and child, the ultimate betrayal.
I don't recall a more tragic case. Two men, each with the support and respect of their community, left in disbelief when one guns the other down-- following a routine lunch!

ETA: Mullins had known the Sheriff's daughter her entire life. Her dad was his bailiff for 14 years until he became the Sheriff. In a town of only 1700, I don't think it so strange he'd have her phone number. She may have even been instructed from an early age to call Mullins if dad or mom not available. (Example-- CBS Blue Bloods. If Lenny Ross' daughter's number was saved in Frank Reagan's phone, would you assume something nefarious going on between the Police Commissioner and Lenny's kid)?
