I think the crime is "enhanced" to CDV because the victim was his wife/girlfriend
mj would probably know
Bingo.
At least in NY and I'm assuming this is similar in Colorado and for that matter most jurisdictions, we have specialized "parts" (essentially courtrooms) that deal solely in DV issues, and charges that can be enhanced if the victim is a crime of domestic violence, i.e. wife/girlfriend or immediate family member.
He'll have bond or bail set on him when he's arraigned in the morning, as even if the enhancer upgrades his misdemeanor to a felony, unless he seriously fucked someone up or beat them half to death (and I'd assume then he'd be charged with something much more serious than criminal tampering), this isn't something people get remanded for.
