A New York jury on Monday began considering the fate of British socialite Ghislaine Maxwell, accused of recruiting and grooming young girls to be abused by late financier Jeffrey Epstein.

Maxwell, the 59-year-old daughter of former newspaper baron Robert Maxwell, faces an effective life sentence if convicted on all six counts following a high-profile three-week trial in Manhattan.

The 12 jurors deliberated for about an hour following several hours of closing arguments and lengthy instructions from judge Alison Nathan about how they should weigh the sex trafficking charges.

They must reach a unanimous decision on each count. If they cannot agree, then the judge could declare a mistrial.

The jurors will resume deliberating on Tuesday morning. It is unclear how long they will take to reach a verdict.

During summations Tuesday, US prosecutors said Maxwell was a "sophisticated predator who knew exactly what she was doing."

Maxwell's defense team countered during its own closing arguments, arguing that there was a "lack of evidence" to convict.

"It is time to hold her accountable," prosecutor Alison Moe said, summing up the government's case.

American money-manager Epstein, 66, killed himself in jail two years ago while awaiting his own sex crimes trial.

Moe said Maxwell was "the key" to Epstein's scheme of enticing young girls to give him massages, during which he would sexually abuse them.

"They were partners in crime," she added.

Moe cited bank records showing that Maxwell received $30 million from Epstein between 1999 and 2007 as evidence that her participation was motivated by money.

Maxwell, wearing a cream pullover and black mask, regularly made notes that she passed to her defense counsel as Moe recounted lurid testimony given by four accusers.

Two said they were as young as 14 when Maxwell allegedly began grooming them and arranging for them to give massages to Epstein that ended in sexual activity.

One, identified only as "Jane," detailed how Maxwell recruited her at summer camp and made her feel "special."

She said sexual encounters with Epstein became routine, with Maxwell sometimes present.

Another, going by "Carolyn," said she was usually paid $300 after sexual encounters with Epstein, often by Maxwell herself.

A third alleged victim was Annie Farmer, now 42, who said Maxwell fondled her breasts when she was a teenager at the New Mexico ranch owned by Epstein.

Laura Menninger, for the defense, questioned the women's ability to recollect quarter-century-old events, accusing them of seeking to profit from payouts from Epstein's estate.

They "all changed their stories when the Epstein compensation fund opened up," Menninger told the court.

Maxwell's attorneys rested their case on Friday, putting just nine witnesses on the stand over two days as they struggled to find people to testify for the defendant.

They called psychologist Elizabeth Loftus, an expert on "false memories," whose testimony was intended to challenge the recollections of the accusers.

The defense also argued that Maxwell was being used as a "scapegoat" for Epstein's crimes after he evaded justice.

"There is no evidence that Ghislaine Maxwell groomed any of the four," Menninger said, urging the jury to acquit on all counts.

The socialite declined to take the stand but made a brief statement to the judge on Friday.

"Your honor, the government has not proven its case beyond reasonable doubt so there is no need for me to testify," she said.

The trial had been expected to last into January, but Maxwell now faces the possibility of learning her fate before Christmas Day, her 60th birthday.

The charges stem from 1994 to 2004. Maxwell pleaded not guilty to all counts, which carry a total of up to 80 years behind bars.

Conspiracy to commit sex trafficking of minors carries a maximum 40-year sentence. The lesser charges have terms of five or ten years.
