Events of GTA V
Rivaly with Trevor
- "I just spoke to that maniac Trevor. He's coming. Get down to the meth lab to protect it."
- ―Elwood informs his brother of Trevor's arrival.
The Los Santos Triads, who seek to expand their business in Blaine County, choose to partner with the O'Neil instead of Trevor due to the latter's violent and reckless behaviour. Hearing about the partnership from Tao Cheng's translator, an enraged Trevor decides to destroy the O'Neil farm as retribution for stealing his potential associates; he phones Elwood, who tells him it was business and Trevor can come to discuss about the partnership at the farm. But Trevor dismisses it and tells Elwood of his intentions to attack the farm.
Fearing of Trevor's attack, Elwood informs his brothers of the psychotic drug dealer's arrival, telling his family to protect the meth lab from Trevor, while Elwood and two of his brothers drive to meet up with the Cheng family.
However, despite his family's best efforts, the O'Neil brothers are slaughtered by Trevor, who finishes his rampage against them by pouring gasoline in-and-outside the lab before blowing up the farm.
- "I'll be back to revenge myself."
- ―Elwood to Franklin, moments before his death.
Elwood and the remaining O'Neils are later tailed by Trevor's associate Franklin Clinton on Trevor's request, as the O'Neils have heard of Trevor's return to Sandy Shores. The O'Neils attempt to escape from Franklin, but a doe on the road leads to their crash and subsequent escape into a forest.
Elwood's remaining brothers are shot dead by Trevor's associate Michael De Santa, but Elwood hides behind a rock and fire rockets towards Trevor and Michael, who can't get a clear image of Elwood. Elwood is found by Franklin, with the help of Chop, and attempts to run away, yelling at them that he'll return to avenge his family by himself, only to be gunned down by Franklin.
