Micheal Madsen's son Kalvin mourns over the 'suspected suicide' of his brother ...

Reservoir Dogs actor Michael Madsen's son, Kalvin, is mourning the loss of his older brother, Hudson, the day after he was found dead in a suspected suicide in Hawaii.

Kalvin Madsen, 25, was photographed Tuesday on the balcony at his mother's Los Angeles home looking solemn with his head hanging down.

He appears heartbroken over his brother's death and, according to a tribute posted on his Instagram account, is 'not emotionally available' to talk about Hudson's death right now. He did, however, invite his followers to message him to share their found memories of his brother.

His girlfriend of two years, Lola, was also spotted arriving to the property with a suitcase and another woman, likely someone who was also close to Kalvin.

Hudson Madsen, the 26-year-old godson of Quentin Tarantino, died from an 'apparent self-inflicted gunshot'.

He is the oldest son of actor Michael Madsen and his ex-wife, actress DeAnna Madsen. The couple also shares a 16-year-old son, Luke.

Michael has said he is 'heartbroken and overwhelmed with grief and pain' after his son Hudson was found dead in a suspected suicide in Hawaii.

His family have since paid tribute to the Afghanistan veteran, saying in a statement to Metro: ‘We are heartbroken and overwhelmed with grief and pain at the loss of Hudson.

‘His memory and light will be remembered by all who knew and loved him. We ask for privacy and respect during this difficult time. Thank you.'

DeAnna, 61, was traveling to Hawaii to deal with the tragedy, a source told the publication.

A spokeswoman for the Department of the Medical Examiner in Honolulu said earlier: 'I can confirm Hudson Lee Madsen, 26, died by a gunshot wound to the head in a suspected suicide on the island of Oahu.'

Hudson is survived by his wife, Carlie, and since August 2019 had been living in Wahiawa, Hawaii after serving time in the U.S. Army.

Kalvin posted a series of photos to his Instagram account in a tribute post to his brother. He said he is 'not emotionally available' to talk about Hudson's death right now. He did, however, invite his followers to message him to share their found memories of Hudson. In the above photos, Kalvin and Hudson are seen together at various point in life

Hudson was based at the Schofield Barracks in Oahu, home to the 25th Infantry Division, and in March was promoted.

Last week, on January 15, Carlie underwent surgery and paid tribute to her husband for his support.

'I just want to give a shout-out to my amazing husband!' she wrote on Instagram.

'Yesterday I had surgery to remove a tumor from one of my breasts and he was and has been so patient throughout this whole process!

'We were at the hospital for about 7 hours yesterday and while I was in surgery he went to target and got me flowers, comfy pajamas, my favorite candy and a card! He's also been amazing in helping with my recovery and I'm just so thankful!

'I also want to thank my family and friends that have reached out to make sure I'm okay and to check in on me! I love you all so much.'
