Building security stood outside OnlyFans model Courtney Clenney’s luxury Miami apartment and “did nothing” for several minutes as she allegedly knifed her boyfriend to death, lawyers now claim.

Security at the Miami high-rise where Clenney lived with her boyfriend, Christian Obumseli, was first notified of a fight inside the couple’s 22nd-floor unit — and stood outside their apartment door for 12 minutes — before Clenney herself called police and said she had fatally stabbed him, according to a lawsuit filed by Obumseli’s estate.
