BOSTON » Jurors in the trial of Boston Marathon bomber Dzhokhar Tsarnaev (joh-HAHR’ tsahr-NEYE’-ehv) heard descriptions of horrendous injuries from survivors, then saw a video of Tsarnaev minutes after the explosions walking calmly into a Whole Foods store to buy a half-gallon of milk.

The juxtaposition by prosecutors apparently was aimed at supporting their contention that, after planting and detonating two bombs with his brother, Tsarnaev went about his life as if nothing had happened. The blasts on April 15, 2013, killed three people and injured more than 260.

Jurors heard Monday from Jessica Kensky, a newlywed who described trying to shield her husband from seeing his mangled leg and being pushed to the ground by a bystander frantically trying to extinguish flames on her body.

Testimony is scheduled to resume Tuesday.
