A Pennsylvania woman accused of conspiring in her boyfriends robbery and shooting death earlier this year was arrested on Wednesday, the district attorneys office in Montgomery County announced.

Katherine Emel, 29, was charged with second-degree murder, robbery and conspiracy in connection with the death of William Carter, 35, her boyfriend, who was found dead on Jan. 20 in Norristown, a suburb of Philadelphia. Prosecutors say one of the men who robbed and killed him had been tipped off by Emel about Carters recent gambling winnings.

According to the news release, surveillance footage showed three people exiting a vehicle to ambush Carter after he crossed the street to get money from his car. Police said a fourth person, the driver, remained inside the vehicle.
