Eighteen months after injuring his brain in a 2012 avalanche, Dutch Prince Johan Friso died Monday, Aug. 12 at the age of 44. The Dutch royal house tells The Associated Press that Friso's death was due to complications from the accident.

On Feb. 17, 2012, Friso was buried in an avalanche while skiing off-trail in Lech, Austria. He was unconscious after rescuers pulled him from the snow 20 minutes later, and remained in a coma for months. The royal house says the prince only ever regained "minimal consciousness."

Prime Minister Mark Rutte said Friso's death still "comes as a shock," explaining, "Prince Friso was only 44 years old, and until the ski accident, in the prime of his life."

Friso is survived by wife Princess Mabel, 45, and daughter Luana, 8, and Zaria, 7. The prince gave up his claim to the throne when he married Mabel Wisse Smit in April 2004 without parliamentary approval. The couple was cut from the royal house after trying to cover-up Smit's past relationship with drug baron Klaas Bruinsma.
