On the afternoon of 3 January 2008, Speight discovered
Natasha Collins's body in the bath at their
St John's Wood flat in north-west London and called emergency services. He told police that he and Collins had spent the previous evening drinking wine and vodka, and taking
cocaine and
sleeping pills. Speight was questioned by police and was arrested on suspicion of murder and of supplying
class A drugs. He was released on bail until the first week of February. Because of this, the
BBC cancelled the Saturday repeat edition of
SMart. An
inquest, which opened on 8 January 2008, heard that the death was not thought to be suspicious but should be "subject to further investigation". At that point, police were awaiting results of
toxicology tests after a
postmortem examination was inconclusive. Speight denied any involvement with Collins's death, In April 2008, the coroner recorded a verdict of
death by misadventure in relation to Collins. The cause of death was "cocaine toxicity and immersion in hot water", according to the consultant pathologist. The inquest found that she had taken "very significant" amounts of cocaine with sleeping pills and vodka, and that she had suffered 60% burns to her body, including her tongue. Speight planned to meet Collins's mother at
Covent Garden for coffee on the afternoon of 7 April. He was dropped off at
Wood Green tube station that morning, but never appeared at the planned meeting. Speight missed an appointment with a counsellor, but this was because of confusion over dates. Two police officers spoke to him, as he appeared vacant, distracted and "deep in thought", but he refused their help. He was captured on CCTV in the afternoon taking money from a cash machine at
Queen's Park station, and subsequently boarded a southbound
Bakerloo line train. ==Death and inquest==
