A surveillance camera captured footage of a woman shooting her ex-boyfriend as he walked away from her Marigny home after an argument last week, New Orleans police said in court documents released Tuesday.

Troy Cooks died over the weekend, and police late Monday booked Crystal Baumann on a count of second-degree murder.

Baumann had initially been jailed on a count of aggravated battery by shooting. Cooks' death prompted police to upgrade the count against her. Second-degree murder is punishable by life imprisonment.

In the last several months, Baumann, 33, had filed Civil District Court complaints accusing Cooks of breaking her phone, slapping her, refusing to leave her home and sending text messages about the two having sex to her friends and relatives.

She also said Cooks destroyed her security cameras and spray-painted her place when she previously lived in Central City, and she expressed a desire to "settle this matter as positive as possible."

Baumann obtained two temporary restraining orders barring Cooks from coming near her or contacting her. But neither was in effect by early August, when she failed to show up for a key court hearing in the case.

About 12:30 p.m. Friday, police officers responding to gunfire at Baumann's home in the 1900 block of North Rampart Street found her standing over Cooks, who had a bullet wound to his head.

Baumann admitted she had shot Cooks — who would have turned 30 on Tuesday — and she was taken in for questioning.

A warrant for Baumann's arrest says investigators recovered a surveillance video clip showing her gunning down Cooks "from the rear" as he walked away from her home. The warrant also says that an unidentified witness saw Baumann arguing with Cooks on the front porch, heard a gunshot and then saw Cooks fall to the ground. Cooks died the next day.

Baumann's recent civil filings against Cooks were not the first time he had been accused of menacing behavior.

Criminal District Court records show he had pleaded guilty in 2009 to charges of simple criminal damage to property, unauthorized entry of an inhabited dwelling, resisting police, simple battery and violation of protective orders, which are often issued to people accused of domestic abuse.

He received two years of probation for those pleas, which resulted from at least two separate incidents, court records show. Details about those incidents weren't available.

Criminal District Court Magistrate Judge Harry Cantrell on Tuesday set Baumann's bail on the murder count at $250,000.
