DES MOINES, Iowa -- A Polk County jury will have to decide if a Clive toddler died at the hands of her mother's boyfriend, or from a tragic accident.
Joe Lopez is charged with first degree murder and child endangerment.
20-month-old Ruby Alvarez was rushed to the hospital with a skull fracture and broken ribs in November of 2014.
Lopez claims she fell out of the high chair. However, prosecutors say that explanation doesn't add up.
Jurors heard opening statements Friday and the trial resumes Monday morning.
