WASHINGTON, April 29 (RAPSI) – Judy Clarke, an expert in federal death penalty cases, has joined a public defense team representing suspected Boston Marathon bomber Dzhokhar Tsarnaev, according to court order made available to RAPSI.

US Magistrate Judge Marianne Bowler at the US District Court in Boston ruled on Monday that appointment of Clarke, a California-based attorney, “is… justified to provide the defendant with adequate and proper representation.”

Clarke has built her reputation by defending the Unabomber, Tucson shooter Jared Loughner, Ted Kaczynski, Atlanta Olympics bomber Eric Rudolph, and scores of other high-profile criminals, the Boston Globe reports.

All her clients received life sentences instead of the death penalty.

Tsarnaev also requested appointment of David Bruck, a clinical professor of law at Washington and Lee University School of Law and director of the school’s death penalty defense clinic, but this motion was denied.

At present, he is also represented by three attorneys: Miriam Conrad, the federal public defender for the District of Massachusetts; Timothy Watkins, and William Fick, each assistant federal public defenders for the District of Massachusetts.

Two blasts occurred on April 15 at the finish line of the Boston Marathon, America's most prestigious 26.2-mile race boasting such stringent entry requirements that only the best of the best are entitled to compete.

Three people have been confirmed dead, including an eight-year-old boy present to cheer on his father. More than 180 people were reported as injured.

Brothers Dzhokhar and Tamerlan Tsarnaev, aged 19 and 26 respectively, are suspected of having detonated two bombs made from pressure cookers at the Boston Marathon. Tamerlan was killed in a shootout with police the following Friday. Dzhokhar was captured several hours later after a manhunt that shut down much of Boston and the surrounding areas.

Dzhokhar is charged with one count of using and conspiring to use a weapon of mass destruction, namely, an improvised explosive device, “against persons and property within the United States resulting in death,” and one count of malicious destruction of property by means of an explosive device resulting in death.

Both charges carry the death penalty.
