Police say they have no positive connections between the image of the man and Flores' murder. However, HPD says the description of Flores' killer is close to the description of the man recorded in the surveillance video.
Flores was fatally stabbed on May 17 while walking home from attending classes at Marshall Middle School in north Houston.
The FBI announced Wednesday the reward for information leading to his arrest has risen to $45,000.
Congresswoman Sheila Jackson Lee appealed to undocumented persons for information during the same press conference. She says regardless of immigration status, eyewitnesses should come forward with information about Flores' death without fear of retaliation because "certain protections" are available.
