Update: A preliminary hearing for Mandy Gumm has been continued until March 26.
A Pittsburgh woman faces a preliminary hearing today in Coraopolis on charges she threatened a woman who was expected to testify against her boyfriend in court.
Mandy Gumm, 26, contacted a woman in Moon Township and threatened to harm her if she testified against Gumm's boyfriend, 23-year-old Brandon Brown, of Pittsburgh, police allege in a criminal complaint.
Police did not release the name of the victim involved in the incident.
Moon Police charged Brown with an early morning armed robbery in January. Police said Brown pointed a gun at a cab driver's head in Moon Township's Mooncrest neighborhood and demanded cash. The driver fled and was unharmed in the incident.
Brown is charged with felony robbery and aggravated assault alongside 23-year-old Lynard Grace, of Pittsburgh.
Moon Police Detective Joseph Brace wrote in a complaint that a woman turned over several voicemails she said were left by Gumm, who threatened to "travel to Moon Township" to assault the woman, who was expected to act as a police witness in connection to the robbery.
Police also obtained phone recordings of Gumm speaking with Brown from the Allegheny County Jail, in which Brown instructs the woman to contact the witness "so she don't (sic) come to court."
Brown elaborates in the conversations that the victim "turned the state on me," and that "if they (police) contact my school I'm going to be expelled."
Police obtained a warrant for Gumm's arrest, and she turned herself in on March 7. She is charged with intimidation of a witness.
Brown, who remains jailed, is also charged with intimidation of a witness. He is scheduled to appear for a preliminary hearing on March 23.
