"I didn't kill him, but I knew it all revolved around me."
That's what Shanika Robinson told a packed courtroom.
Prosecutors say she, her brother Leon and boyfriend Isiah Genus (who has already pleaded guilty) murdered pizza mart owner Shahabuddin Rana in August 2009 over money.
Rana - a Pakistani immigrant - paid her $500 a week to marry his younger brother, so the younger brother could get a green card.
But after an immigration judge ruled the marriage as a sham, the older Rana stopped paying her.
Prosecutors say an angry Robinson went to the pizza mart with her brother and boyfriend and killed Rana. But on stand Wednesday said the men were arguing when she left the mart, and only learned later Rana was murdered.
Then she said her husband, Rana's brother, turned to her for help and she ran the pizza mart for the next week, until police showed up one day and arrested her there for the owner's murder.
Robinson told her questioners that another boyfriend, Terrence Greene, was a MPD officer. Greene, a married detective, hanged himself before he was questioned
