On January 16, the medical researcher was shot outside her home near Augusta and Woodway in the Tanglewood area. Police have no idea who may have killed Bagherzadeh or why.
"It's been four months since my sister was senselessly murdered behind our home. These past four months have been unimaginably hard on all of us," said the victim's brother, Ali Bagherzadeh.
Police hope the $200,000 will prompt someone to come forward with information about the murder.
Police ask anyone with information about the murder to contact Crime Stoppers at 713-222-TIPS.
