Prosecutor Justina Geraci alleged Escobar lured the men to their deaths after she convinced the gang that the victims "had mocked them" by using MS-13 symbols.
“You heard [MS-13 gang member] David Gaitan-Rivera’s testimony,” Geraci told the jury.
“He told you how one of the victims had reached for [Escobar] before he was killed and his blood had gotten all over her shirt.
“He told you how she licked the blood off her lips.
“And how just before [victim] Michael Lopez was hacked to death, how she smiled."
According to reports, Escobar smiled and joked with her defense team as the prosecutor spoke
During her trial, jurors were presented recorded phone calls Escobar had with her boyfriend, an MS-13 member.
Assistant US Attorney Paul Scotti told the court: "She was telling her boyfriend exactly what happened.
“She told him she killed those four young men and she was happy about it. She was happy.”
But Escobar's lawyers claimed she didn't know the victims would be attack as she lured them to the park as defense attorney Jesse Siegel argued his client wasn't a member or associate of the gang.
“Not every girlfriend is an associate,” Siegel said.
“Her boyfriend was a homeboy.
“She was there. She certainly didn’t prevent it from happening. The issue is if she knew something was going to happen.”
The trial closed yesterday after closing statements, with jury deliberations due to start today.
