A Capitol Heights woman convicted of murder in the death of her brother-in-law was sentenced to 54 years in prison Friday.

Shanika Robinson, 28, and Leon Robinson, 27, were convicted of first-degree murder and other charges in August. Leon Robinson was sentenced to nearly 76 years in prison.

She was convicted of five of the seven charges against her, including conspiracy and burglary, in the 2009 murder of her brother-in-law, Shahabuddin Rana, 44. A D.C. Superior Court jury found him guilty of all seven charges against him, including first-degree premeditated murder.

Because the jury found that Rana’s slaying constituted “aggravated circumstances,” the Robinsons faced life in prison without parole.

Prosecutors said Shanika Robinson orchestrated a plot to murder Rana after he stopped paying her $500 a week in exchange for marrying Rana’s younger brother Allauddin, who had come to the United States from Pakistan in 2006, to help him obtain U.S. citizenship.

But when immigration officials discovered that the marriage was a sham, and Rana learned of Robinson’s other lovers, Robinson devised a plan to kill him, prosecutors said.

A third man, Isaiah Genus, 28, the government’s star witness pleaded guilty to second-degree murder and testified that he planned the murder with the Robinsons. Genus is scheduled to be sentenced in November.
