A missing Melbourne man was likely dead and his remains kept inside a nearby home the entire month his parents desperately searched for him, police have alleged.

Joshua Bishop, 23, was last seen by his housemate at their Lalor Cres home in Sunbury on May 27.

He was reported missing by his mother two days later, with a full scale search operation launched to find him.

Heartbreakingly, the body of the apprentice carpenter turned personal training student was found only 30 minutes away from home.

Police discovered human remains believed to be Bishop’s in a home on Erinbank Cres in Westmeadows on Saturday.

Brandon Watts, 27, was charged with his murder on Sunday night.

Watts faced the Melbourne Magistrates Court on Monday.

Police in court alleged Bishop was dead, and his body left at the Westmeadows home, ever since he first went missing more than a month ago.

It’s understood the accused family members were also living at the home at the time.

“For this to happen to him, that makes no sense,” Bishop’s father Travis told 7NEWS.

“He was such a beautiful kid.

“We’re in Australia, this is the lucky country, and we’ve had our son taken from us. Murdered. And left to rot, it’s not fair.”

Broadmeadows Valley Park, where Bishop’s phone pinged the day he was last seen, backs onto the street of the Westmeadows home.

The park had been searched by police at least twice before they made the grim discovery nearby.

“I’m so angry, I just want justice,” Travis said.

“I want justice for our son, our baby boy. I don’t think this will ever be closure. There’s a piece of us taken away.

“He’s always the boy who wanted to help everybody, and he put everyone else before himself.”

Watts did not apply for bail and is expected to next face court on September 22.
