Two sons of an ailing bestselling true crime writer are accused of defrauding and bullying her into giving them more than $125,000 - despite the pair already receiving a monthly allowance of $25,000 combined with their two sisters through their mother's corporation. Ann Rule's son, 54-year-old Andrew Rule, is accused of bullying her into giving him $23,327, according to court documents, and admitted to authorities that he blew the money given to him on gambling and strip clubs. Michael Rule, 51, who receives approximately $9,000 a month between salaries paid to him and his wife by Rule Enterprises, LLC, is accused of forging his mother's signature on her checks from March 2014 to February 2015 amounting to $103,628. Prosecutors have filed a restraining order against both men to stay away from Ann Rule, and the two sons accused of wrongdoing are set to appear in court on April 30. Famous true crime writer Ann Rule (above), 84, had more than $100,000 allegedly stolen and defrauded from her by her two sons . Ann Rule, 84, is known for many of her crime books, notably the 1980 bestseller The Stranger Beside Me based on serial killer Ted Bundy. She has published 33 books and eight of those have been turned into movies including Ann Rule Presents: The Stranger Beside Me and Small Sacrifices. The Washington-based author has been in declining health since 2013 after she broke her hip, she also suffers from periods of extreme confusion and is vulnerable to undue influence, according to the Huffington Post. Court documents also said she is 'largely confined to a wheelchair', is unable to 'perform many activities of daily living without assistance' and 'she is on oxygen at all times'. Her son-in-law, Glen Scorr, alerted authorities in March after he became suspicious that she was being 'financially exploited' by her two sons. An investigation revealed that Michael and Andrew Rule along with their two siblings, Leslie and Laura, receive an estimated $25,000 monthly salary combined through their mother's corporation Rule Enterprises LLC for work they perform on her behalf, according to court documents. The four children also have their health and dental insurance covered through the corporation. Andrew Rule, who also has his rent and car insurance covered by his mother, would allegedly bully her until she would give in and write him a check, according to court documents. 'Andy would pester and bully Ann relentlessly for money, sometimes threatening suicide, sometimes trying to make her feel guilty, sometimes screaming obscenities at her, until she would finally give in and write him a check,' the documents stated. Authorities said he would have an excuse for needing money which included when he got injured and needed money for medical expenses, repairing his car, groceries, buying a racehorse and needing clothes after getting a new job. Andrew Rule (pictured above), the son of  author Ann Rule, has been charged with theft by deception in a case of alleged financial exploitation of his mother's money. His brother, Michael Rule, has been charged with theft and forgery . A protection order was granted against Andrew Rule on February 3 prohibiting him from having any contact with Ann Rule except for under limited circumstances, according to court documents. However, authorities said he violated it and was arrested on March 27. While in custody, he told officers he battled with gambling and drug addictions for years, and that he used the money given to him by his mother on gambling and strip clubs. He also told officers he pressured his mother for money never intending to use it for the stated purposes, according to court documents. 'I have never in my life, as God as my witness, stolen anything whatsoever from my mom,' Andrew Rule told KIRO-TV. 'Basically I used to have a gambling problem but I don't anymore and I have absolutely no idea why I was pulled in at the same time my brother was,' he continued. He has been charged with first-degree theft. Michael Rule, who reportedly receives a higher salary than his siblings because he is more involved in his mother's day-to-day care, is accused of forging her signature on her checks, according to court documents. Prosecutors have filed a restraining order against both men to stay away from Ann Rule, and the two sons accused of wrongdoing are set to appear in court on April 30. Ann Rule is known for many of her crime books including The Stranger Beside Me based on serial killer Ted Bundy . Ann Rule told authorities that she did not give him permission to write himself or his wife checks for funds exceeding their salary without her permission. She also confirmed the checks written with her signature was not hers and that it appears to be the signature of Michael Rule, according to documents. Authorities said that once the protection order was filed against Andrew Rule, Michael Rule 'began engaging in similar tactics of intimidation and coercion to pressure his mother to provide him funds above his monthly salary'. 'He became increasingly insistent he needed the money to pay his mortgage and other expenses. He would yell at his mother demanding money as she cowered in her wheelchair,' the documents stated. Ann Rule told authorities in an interview that Michael Rule would fly into rages throwing things across the room and sweeping a counter clean with his arm. A family friend, John Patrick Kelly, who was hired as a handyman by Ann Rule stated he had previously been physically assaulted by Michael Rule, according to court documents. Michael Rule has been charged with first-degree theft and forgery, and both men are out of jail on personal recognizance, according to KIRO-TV. Authorities said the fraud loss amount is expected to rise as more documents are received and reviewed, and the investigation is ongoing.
