His mother Marioa Shriver, who was with him on the beach, called emegency services.“What’s the emergency, ma’am?” asked the 911 operator.

“It was a boogie boarding accident” replied Shriver, who is fighting her estranged husband for financial support. "He can’t move off the beach… broken ribs or something like that.”

Shriver told the operator it was her son, Christopher, 13, who was hurt. She described his fragile condition: “He’s awake and breathing. He can’t move. He’s having trouble breathing.”

Arnold Schwarzenegger has visited Christopher in the intensive care unit and Maria Shriver has been at his bedside throughout. They issued the following statement:

“While it has been a very scary week, Christopher is surrounded by his family and friends. He is a brave boy and is expected to make a full recovery.”

The couple’s oldest son, Patrick, tweeted “this kid is strongest kid I have ever seen … keep praying.”

And his sister, Katherine, also posted a message on Twitter: "Thank you guys for ur concern and prayers for my baby brother!" she wrote. "He's a tough little guy and getting better! Please keep praying for him!"
