A sister has told of her “unbearable” grief after her 32-year-old brother was found dead in his flat in London.Cher'ree Lambert was last night still trying to find out how Dennis Lambert, who battled drug problems in recent years, died earlier this week.Ms Lambert, 36, of Devonshire, got a call from a cousin on Wednesday morning to say her brother was found in an unresponsive state at his apartment in Thornton Heath, Croydon.“It's unbelievable,” she told The Royal Gazette. “When they called me yesterday I was in pure hysteria. I just couldn't bear it.“It's one thing to expect death but it's another to actually realise that someone so young could die. How is that possible?“Yesterday was a really hard day; I cried all day. When I first got up this morning, the crying started again.”She described her brother as a kind-hearted gentleman and ladies' man with a “gorgeous smile”.“He was the type of person that if he had it, you could have it,” she said.Mr Lambert, father to Dennikia, ten, and six-year-old Dennika, moved permanently to the UK six months ago, according to his sister.She said he was previously there for drug rehabilitation and decided to return because he couldn't get a job in Bermuda.“This just wasn't the environment for him to get ahead or get better so he decided to go back there and stay,” said the mother-of-three.“You come out of rehab here and you are right back on the corner where you left.“When I did speak to him I could tell that he was getting along and that he was enjoying where he was. The thing he missed most were his daughters.“They both know now [about his death]. Yesterday, only the oldest one knew and she was not taking it very well. She dotes on him. That's her dad and there's nothing like him. She is very much like him, her spirit happy, happy, happy.”Ms Lambert, an emergency medical dispatcher, talked to her brother on Monday, when he called from England to wish her a happy new year. “He seemed perfectly fine,” she said. “Conversations with him always ended ‘I love you' even when he was here and he called me every week.”He said nothing to suggest he was using drugs again, she added. “I really didn't get the sense that he was trying to go back that way.”She and her brother were adopted as babies from separate families by Leroy and Joan Lambert and grew up in Southampton, where Mr Lambert attended Port Royal Primary School. He later went to Sandys Secondary School.The siblings' mother died when Ms Lambert was 13 and they lost their father in late 2009. Dennis Lambert worked at the Corporation of Hamilton and the Ministry of Works & Engineering but suffered a bike accident a few years ago that left him with a leg injury.He wasn't working at the time of his death as he had recently had surgery. “I'm thinking that he was taking medication for his leg and I don't know if he decided to take something else with that,” speculated his sister. “He was also suffering from a toothache. I know you can't mix some medications.”She said local pastor Leroy Bean was trying to help her get some answers from the authorities about her brother's death. She plans to fly his body back to the Island.A Metropolitan Police spokesman said he could find no record of the death, possibly because it was not suspicious. A Bermuda Police Service spokesman said police here had not been notified by UK police but that was not unusual in the case of a non-suspicious death.
