PA Mayor to Limit Police Cooperation with Immigration Officers: Philadelphia Mayor Michael Nutter is expected to sign an executive order to limit collaboration efforts between his city's police department and federal immigration authorities.  Julie Shaw of Philly News reports that the order would prevent police from honoring detainer requests by Immigration and Customs Enforcement unless the case involves a person convicted of a first or second-degree felony.  Prior to this order, ICE officials were able to request that a person suspected of being a non-citizen be held by city police up to 48 hours until immigration officers could take custody of them.

CO Police Suspect Accused Murderer was Hallucinating from Marijuana: Denver police are investigating to determine if a man accused of fatally shooting his wife Monday was hallucinating from edible marijuana.  Paresh Dave of the Los Angeles Times reports that the man's wife called 911 Monday night and told the dispatcher that her husband was "talking about the end of the world" and hallucinating, and mentioned that he may have eaten some marijuana. During the 911 call, 47-year-old Richard Kirk retrieved a gun from a locked safe and shot his wife in the head while the couple's three children hid in a bedroom.  Kirk was arrested on suspicion of first-degree murder, but has not yet been officially charged.
