Mum charged with killing her one-year-old son after ‘kissing him then throwing him off bridge’

A one-year-old little boy has died, six days after his mum allegedly threw him off a bridge into a river.

Zymeir Perry died in hospital Sunday morning after his mum Johnesha Monae Perry, 19, allegedly flung him off a bridge in Pennsylvania, US.

Ms Perry gave Zymeir a kiss moments before she pushed him over the railings and then jumped from the 52-foot bridge into the Lehigh River herself.

A police officer found the little boy 700 yards away, floating downstream, and performed mouth-to-mouth resuscitation.

Ms Perry suffered serious injuries in the fall but managed to get to the shore.

An autopsy is expected to take place on yesterday morning to determine his cause of death.

Ms Perry has been charged with attempted homicide, endangering the welfare of a child and aggravated assault.
