Lisa eventually proposes that the group murder Bobby. Ali recruits her new boyfriend, the pot-smoking and acid-dropping Donny (Michael Pitt), and his troubled friend, Heather Swallers (Kelli Garner), who has recently been released from rehab; Lisa recruits her cousin, the shy and nerdy Derek Dzvirko (Daniel Franzese). They initially plan to kill Bobby with a gun stolen from Lisa's mother. Ali and Lisa take Bobby to the Everglades, with the plan that Lisa will shoot him while he has sex with Ali, but Lisa finds herself unable to do it. Realizing they need help, the group hire a supposed "hitman", Derek Kaufman (Leo Fitzpatrick), a friend of Ali's who is in actuality a tough-talking young man several years older than them.
