A man killed his friend by smashing his skull with a rock, a jury has been told.
Michael Wayne Carroll - known as Wayne - bludgeoned Alexander Blick to death in Matlock’s library gardens, a court heard.
Carroll, 44, of Upper Greenhill Gardens, Matlock, is on trial after denying the manslaughter.
Nottingham Crown Court heard this week that the pair were part of a group in the town who spent much of their time drinking alcohol in Hall Leys Park.
But a day-long drinking session ended in tragedy and Mr Blick’s body was discovered on Sunday, October 16 2011, in the gardens off Steep Turnpike.
Caroline Bradley, prosecuting said Carroll had mental health problems, yet to be formally classified but likely to be schizophrenia.
After his friend’s death, blood-splattered shoes were discovered at his flat along with blood-stained clothing, hidden in bushes close by.
Miss Bradley said: “The defendant knows full well what he did was wrong and shortly after the incident attempted to evade responsibility by disposing some evidence, particularly clothing he had been wearing at the time he killed Mr Blick.”
She added Carroll later confessed the killing to two friends saying he had “hit him twice on the head and once in the windpipe.”
But Carroll has denied ever making the confessions.
Witness Jamie Knowles said he had known Wayne for about 15 years.
He said he had been drinking with the pair on October 15, 2011.
He added Carroll “behaved a bit different because he was on speed.”
Mr Knowles said he had taken speed around the back of the library that day and had been drinking vodka. He said the group appeared to be “merry” but added: “Wayne and Alex argued, I think they were drunk. I don’t know what it was about.”
Mr Blick, 42, of Dale Road, Matlock Bath, was originally from Plymouth. He moved to Matlock three months before his death.
The trial continues.
