The man accused of murdering pensioner Don Lock after a road crash has "psychiatric and mental health issues", a court has heard.
The disclosure was made while Matthew Daley appeared at the Hove Crown Court via video-link from HMP Lewes in East Sussex over the death of Lock, 79, last Thursday.
The 34-year-old's lawyer, Barry Cheeseman said: "There are clear psychiatric and mental health issues in this case."

The court was told psychiatric reports will be served by September 21, four days before Daley is due to re-appear in the court for a case management hearing.
Prosecutor Philip Bennetts QC told the court that the Crown would provisionally be ready for any trial in the week beginning October 9.
Remanding Daley back into custody ahead of his plea hearing, Judge Barnes said: "It's clearly a tragic case but it's also a high-profile case."
Daley, of Worthing, is charged with murder and possession of a knife in a public place and is alleged to have repeatedly stabbing Lock after their cars crashed on the A24 at Findon, near Worthing.

Paying tribute at the weekend, Andrew Lock said his father - who was married to wife Maureen for 55 years - was "full of wisdom, full of wit, always calm".
A keen traveller, the pensioner had been looking forward to going on a cruise with his wife next month before heading to Scotland for a holiday.
As well as his wife and son, Mr Lock, a Brighton and Hove Albion season ticket-holder, leaves daughter Sandra, four grandchildren and five great-grandchildren. A sixth great-grandchild was also on the way.
