The mother of a 7-month-old boy found dead in the Connecticut River has testified about the troubled relationship she had with the baby's father.

Tony Moreno is on trial in Middletown on charges that he threw the boy from a 90-foot-high bridge into the river. He has pleaded not guilty to murder and risk of injury to a child.

His ex-girlfriend, Adrianne Oyola, testified Wednesday that her relationship with Moreno took a turn when she refused his marriage proposal in June 2015. The two were working out a custody agreement for their son, Aaden, in the weeks before his death.

Moreno told Oyola in a series of angry texts Aaden was dead in the moments before police officers arrived and saw Moreno himself jump into the river from the bridge.
