Martin Kearney said his brother's partner Charlene and four children were devastated as they laid him to rest on Monday.
His body was pulled from the lake at Alexandra Park on Wednesday afternoon after he went missing when he went to walk his dogs on Tuesday morning.
The animals returned to his home without him and Martin said once Mr Kearney didn't collect his children from school that afternoon "they knew something was wrong".
Martin described his younger brother as "fun-loving" and a dedicated family man.
The incident has been linked to drugs, and Martin admitted: "Kevin wasn't an angel."
But he added: "It's a better system to be brought through the courts and have a fair trial than to have someone step out of a bush and execute you and take your life."
Dissident republicans calling themselves the 'IRA' have claimed responsibility for his killing.
Mr Kearney didn't comment on a second statement read out by masked men in an Ardoyne pub on Monday, in which further threats were made and Mr Kearney's killing was referred to.
He appealed for anyone who can assist the investigation to come forward.
"I appeal for the nationalist community to come forward especially the republican community and assist in these people being brought to justice, and if they can't talk to the police about it, to talk to Sinn Féin," Martin said.
"Help these evil people be brought before the courts."
His words come as detectives revisit the scene of Mr Kearney's murder.
An actor playing the role of Mr Kearney retraced his steps with his dogs Dolly and Shadow as part of a reconstruction.
Detective Chief Inspector Justyn Galloway commented: "We are a week on from the murder of Kevin and the purpose of our reconstruction this morning is we wish to identify witnesses.
"We want to speak to anyone who has not yet come forward who was in Alexandra Park, and who noticed any suspicious activity, any persons who were out of the ordinary and not usually there.
"Come forward to detectives or pass information on in whatever means they are happy to, which we hope will open up new lines of inquiry and assist in our investigation into identifying Kevin's killers."
Police are also seeking information on a silver Peugeot 406 car in the Alexandra Park area that morning, registration number GNZ 8168.
The car was found burnt out at Donore Court in the New Lodge area on Tuesday morning.
Two people arrested on separate occasions in relation to the murder have since been released unconditionally.
