A Chicago federal jury awarded $3 million on Thursday to the widow of a former leader of Reed Smith's corporate department, finding pharmaceutical giant GlaxoSmithKline plc liable for the 2010 suicide of Stewart Dolin.

The verdict was well below the $39 million that Dolin's widow requested. But it was her victory nonetheless, and the culmination of a nearly six-week trial between two sides who seemed to agree on nothing—most importantly, whether the popular antidepressant paroxetine that Dolin took for six days before he threw himself in front of a Chicago passenger train causes suicide in adults.

The jury in effect found it does.
