Former “NYPD Blue” star Kim Delaney won’t face any charges after her recent arrest for felony assault … L.A. prosecutors declined to file any charges against her and her husband, TMZ has learned.

The actress appeared in L.A. County Superior Court this morning after she was arrested Saturday for assault likely to cause great bodily injury against her husband, James Morgan. Morgan was also arrested for misdemeanor domestic violence.

But, the Los Angeles County District Attorney’s Office decided not to file any charges, telling TMZ they didn’t have sufficient evidence to move forward against either of them. It’s a bit surprising after our law enforcement sources say the first incident between the couple popped off Friday night when Kim filed a domestic violence report with police after Morgan left the scene.

Cops said the next morning Morgan returned and things got so heated between him and Kim that she allegedly jumped behind the wheel of a vehicle and tried to mow him down.

The Costa Rican hotel where Brett Gardner‘s family vacationed is taking precautions amid the investigation into Miller‘s death … with officials telling TMZ Sports it has blocked off their room from the public as officials look into whether carbon monoxide played a factor in the tragedy.

Judicial Investigation Agency (OIJ) director Rándall Zúñiga revealed in a press conference that high levels of carbon monoxide were detected in the Arenas Del Mar Beachfront & Rainforest resort room the Gardners reserved during their trip … and noted a “specialized machine room” was located next to their reserved space, which could have led to contamination.

The resort tells us it will continue to cooperate with the investigation … but “out of an abundance of caution, the room in question has been blocked until further notice.”

While the family waits for answers, 14-year-old Miller’s body was released back to his family. In an obituary posted to a local South Carolina newspaper, the family asked for donations to the Make-A-Wish Foundation in his memory.
