Lazarus finds Shamrock walking with his wife and baby and takes a beating before SÃ¡nchez comes to help pin him down while they put the cuffs on him.

Then later at the precinct they find out that he confessed to his wife about his affair and she killed him with a steak knife.
Shamrock continues to stare at Lazarus and he tells Yoda that he saw him in a bar while he was drinking and he knows that he recognizes him.

Yoda goes to Shamrock and advises him that if he mentions anything about any of his officers seeing him prior to his arrest; his girlfriend will be arrested for harboring a fugitive and his baby will be taken away from them.
