Former Assistant Director of the Department of State Services (DSS), Dennis Amachree, has made fresh claims about the death of Nigeria’s former military Head of State, Gen. Sani Abacha, alleging that he died of a cardiac arrest during an intimate encounter with his girlfriend’s younger sister.
The claim is contained in Amachree’s newly released memoir, DSS @40: My Journey Behind the Shield, where he detailed what he described as the events surrounding Abacha’s death on June 8, 1998.
According to the former DSS official, Abacha’s girlfriend, whom he identified only as an Igbo woman, arrived at the Aso Rock Guest House alongside her younger sister, a pharmacist who was in Abuja for a conference.
He alleged that after a brief visit, the girlfriend returned to her hotel, leaving her younger sister alone with the military ruler.
Amachree wrote that around 4:05 a.m., the woman realised Abacha had become unresponsive during an intimate encounter.
“At about 4.05 a.m., as they were getting intimate, the pharmacist realised Abacha had stopped moving. She called out to him, but he was unresponsive and stiff. She checked his pulse; there was none.”
According to him, the woman quietly returned to her hotel before flying to Lagos, after which security operatives tracked her down.
He further claimed:
“My team located and brought her to my office. I interrogated her myself. The first thing she said to me was: ‘I did not k+ll him, he d+ed on top of me.’”
Amachree said her account convinced him that Abacha suffered what he described as a “coitus-induced cardiac arrest,” insisting that this version of events represents “the true position” behind the former military ruler’s sudden death.
Gen. Sani Abacha ruled Nigeria from November 1993 until his death in June 1998. His passing has remained one of the country’s most controversial historical events, with numerous theories circulating over the years. Amachree’s account adds another perspective to the long-running debate, though it remains an allegation contained in his memoir and has not been independently verified.
