Miami-Dade State Attorney Katherine Fernandez Rundle announced the charge against the 26-year-old model during a news conference.
Clenney was arrested Wednesday in Hawaii. Fernandez Rundle said Clenney, who goes by the name Courtney Tailor on platforms like Instagram and OnlyFans, remains jailed in Hawaii while authorities work to have her extradited to Florida.
Fernandez Rundle characterised Christian Obumseli’s April 3 death at the couple’s Miami apartment as the culmination of a “tempestuous and combative relationship” that began in November 2020.
The county medical examiner said in an autopsy report that Obumseli, who worked in cryptocurrency, died from a forceful downward thrust from a blade that went 7.6cm into his chest, piercing a major artery.
According to an arrest report, Clenney acknowledged killing Obumseli but said she was acting in self defense.
She said Obumseli had pushed her and thrown her to the floor, which prompted her to grab and knife and throw it at Obumseli from about three metres away. The medical examiner said Obumseli’s wound could not have been caused by a knife thrown from that distance.
Clenney’s Miami defense lawyer, Frank Prieto, did not immediately respond to messages seeking comment from The Associated Press. He previously told the Miami Herald that Clenney was in Hawaii while in rehabilitation for substance abuse and post-traumatic stress disorder. He said they look forward to clearing her name in court.
