Tim Murphy played by Joseph Mazzello (Simon Birch, Radio Flyer) Grandson to InGen Founder John Hammond and younger brother to Lex Murphy. Very interested in dinosaurs; he not only studied many species but he also had an idolization for Dr. Alan Grant. Tim survived through the T-Rex attack, which left him stranded within the electric Explorer that was entangled in a huge tree. Most memorable would be the 10,000 volt shock that he endured while climbing over the electric perimeter fence, deeming him “the human piece of toast.”
