"Everybody starts thinking, and they say maybe it's connected because they knew each other," Bagherzadeh's friend Kathy Soltani told us.
Beavers, 28, was found dead in his northwest Houston apartment Monday afternoon. Authorities say he was shot multiple times. According to officials, Beavers was last seen at 5:45am as he returned to his apartment after walking his wife to her vehicle. Investigators haven't identified any motives or suspects.
Back in January, 30-year-old Bagherzadeh was murdered as she was driving home from a study session. Police have said Bagherzadeh was talking on her cell phone when she was killed. Nothing was taken from her car.
Bagherzadeh's death has garnered international attention because she was an outspoken critic of the Iranian government and converted to Christianity just before her death. Police say no evidence has been found linking her death to her background or political views, though they continue to explore that possibility.
The last person to see Bagherzadeh alive was her boyfriend -- Cory Beavers, Coty Beavers' twin.
Harris County Sheriff's Office spokesman Thomas Gilliland says investigators have not yet found a connection between Beavers' death and the killing of Bagherzadeh. He says they are pursuing leads.
"This was one at his apartment and my friend was killed behind her home, so there must be some motive behind all this," Soltani said.
Even as some wonder if both murders are linked to Bagherzadeh's role as an activist, her friends and family continue her work.
"Why should we be scared?" Soltani asked. "I mean, fear is your worst enemy, so I think being quiet -- especially for us outside of Iran -- is a shame."
