Gelareh Bagherzadeh was a 30-year-old Iranian-American activist and researcher at MD Anderson Cancer Center who was shot to death on January 15, 2012, in Houston, Texas. She was inside her car near the Galleria area and was on the phone with her ex-boyfriend, Robeen Bandar, when she suddenly screamed and then went silent; Bandar alerted police and went to her location, where authorities found her unresponsive.

Investigators initially considered a possible political motive because Gelareh helped found SabzHouston, an organization advocating democratic change in Iran, and had been publicly critical of the Iranian government. Ten months after her killing, Coty Beavers, the twin brother of Gelareh’s then-boyfriend Cory Beavers, was also shot to death, a development that led authorities to explore a link between the two murders.

Subsequent probes led to arrests in May 2014 and federal charges tied to a family conspiracy; authorities said the killings were connected to family hostility over a daughter’s conversion and marriage. Does anyone have information about Gelareh, her work with SabzHouston, or the events around January 15, 2012?
