The master plan, the 14-year-old told the detective, was to "get a vehicle, harm some people, and leave the area."
The evidence was presented yesterday as Superior Court Judge Louis Hornstine began to consider whether the two juveniles should be tried as adults. The adult charges carry prison sentences of up to 40 years if convicted. In juvenile court, the sentence if convicted is four to 10 years. The hearing is expected to continue today.
Among other evidence presented yesterday, which included excerpts from still-confidential documents, were:
Lovett's journal writings: "We're going to kill people left and right - there's no way around it."
E-mail from a 15-year-old codefendant: "I came here to eat pretzels and kill people and I'm out of pretzels."
Lovett's alleged statement to police: "There are six billion people in the world. A few less will not hurt anything."
Prosecutors have said the evidence reveals that the alleged plot was well-planned and carried a serious potential for violence.
Defense attorneys said it showed that the two juveniles were led astray by Lovett. During cross-examination yesterday, they tried to show that the 15-year-old never acknowledged participating in a potentially murderous plot and that the 14-year-old played the least involved role.
Authorities have charged Lovett and the two juveniles with carjacking and conspiring to kill three Oaklyn students who the boys said bullied them.
Lovett is being held on $1 million bail. The Inquirer is not identifying the juveniles, who are being held in detention.
Authorities said the plot began early July 6 but fizzled at the outset when a motorist whom the three tried to carjack alerted police.
