Jurors deciding the fate George Huguely V are expected to listen to a slew of medical testimony this week as Huguely’s attorneys challenge prosecutors’ account of how his ex-girlfriend died.

Huguely, 24, is on trial in the May 2010 death of 22-year-old Yeardley Love. Prosecutors say Huguely beat her to death, and a medical examiner who is expected to testify has ruled that she died of blunt-force trauma to the head.
