If the evidence demonstrates that the defendant conspired with others to commit robbery and, during the robbery, one of the co-conspirators commits capital murder, the defendant can be held criminally responsible for the capital murder if it was in furtherance of the conspiracy's unlawful purpose and should have been anticipated. See Longoria v. State, 154 S.W.3d 747, 755 (Tex. App—Houston [14th Dist.] 2004, pet. ref'd); Pollard, 392 S.W.3d at 801; Rattler v. State, No. 05-08-01020-CR, 2010 WL 2044880, at *5 (Tex. App—Dallas May 25, 2010, no pet.) (mem. op., not designated for publication); Demus, 2010 WL 277092, at *3. Additionally, evidence a defendant knew his co-conspirator might use a gun in the course of committing a robbery has been held sufficient to demonstrate that the defendant should have anticipated a murder could occur during the commission of the robbery.
