It is with heavy hearts to say that our sweet baby boy Madden gained his angel wings late on April 15th,’ she wrote.

‘We miss him so much and we are having a hard time processing this all.’

Madden Hein, 1,  died after he fell out of a window at the Club House Hotel & Suites in Sioux Falls on April 13

The boy, from Minnesota , was staying at the hotel with his parents and was taken to a local hospital after the fall.

It is unclear how he fell or if the window in the room was open at the time of the incident.

DailyMail.com has contacted the hotel and the Sioux Falls Police Department for comment.

A spokesperson told KELO that the incident is under investigation and is currently being looked at as a ‘tragic accident.’

Kathryn said that her little boy is a ‘real life superhero’ as she announced that his organs will be donated to help others.

A GoFundMe page has been created in Madden’s honor to help support his grieving family.

Kathryn Hein, the boy’s devastated mother, announced that her ‘sweet boy’ had died and shared on Facebook this picture of her and her husband Alex holding his little hand in hospital
