THE victim of a man jailed for attempting to extort money with threatening letters against children is fearful there may be other victims.
The Hills mother believes there may be more victims in the area and is encouraging them to come forward.
After 21 months of self-described "hell", the Rouse Hill mother said she felt justice had been done after the sentencing of a Quakers Hill man for demanding property with menace.
Cris Anonuevo, 44, was sentenced at Central Local Court last Friday to a minimum of 2? years in prison after pleading guilty to 19 offences against 16 families between April 2010 and July 2011.
Letters to the Rouse Hill mother and her husband threatened to kidnap and rape her daughter and infect her son with AIDS.
The family, who handed over the $50,000 demanded of them, said they were so fearful for their children they reported it to police only once Anonuevo had been arrested.
"Our family has been through absolute hell," the mother, who asked to remain anonymous, told the News.
"A lot of people have been hurt and we feel we have been psychologically trashed."
The mother of three said she felt justice had been done by the jail sentence.
"Now it's time to move forward," she said. "We're saddened it came to this.
"He has to pay for his crime but we don't wish him any harm and hope he comes through his sentence and can start again."
She wants to tell other victims to "come out now and feel safe".
The court heard many of Anonuevo's targets were family, friends or acquaintances and he used his knowledge of their addresses and children's names to make specific threats against them.
The typed letters demanded sums between $6000 and $105,000 and Anonuevo threatened to double or triple the amount if it wasn't paid within a certain time period.
He also warned of violence against the families and their homes, including kidnapping female children for four days and raping them, saying: "I love young girls like her.
"The list of what can be done to hurt your family is endless and very real. It is amazing how easy it is to infect a person with an AIDS or hepatitis infected needles.
"A quick bump into [child's name] or [child's name] at a crowded shopping centre is a quiet and effective process," he wrote in several letters.
In sentencing Anonuevo to a maximum of 42 months behind bars, magistrate John Favretto said the offender "preyed upon the vulnerability of children, perhaps the greatest fear a parent can have".
The court heard Anonuevo began his campaign of terror after being made redundant and incurring debts of about $150,000.
Another couple described their "absolute fear and paranoia" after receiving the letter and their surprise in discovering they knew the attacker.
"He's the nicest guy you would ever meet," the man said.
