( CNN ) -- The mother and brother of a 31-year-old woman found strangled with her two young sons in the bedrooms of their home filed a wrongful death lawsuit Tuesday against the alleged killer -- the husband and father of the victims . Christopher Coleman has pleaded not guilty and is being held without bond . Christopher Coleman has pleaded not guilty in the triple homicide police say took place early in the morning on May 5 in the family home in the small southwestern Illinois city of Columbia . `` To strip the culpable party of all financial holdings -- all that he has now and all that he may ever have , '' is the aim of the suit , said a statement accompanying the suit filed in Monroe County circuit court by Angela DeCicco and Mario Weiss , the mother and brother of Sheri Coleman . `` To allow one penny of ill-gotten gain to be derived at the expense of Sheri , Garett and Gavin is not acceptable to those who dearly love them . '' The money would go to a memorial fund set up for Coleman and her sons , Garett , 11 , and Gavin , 9 and `` these funds will be used to erect a lasting tribute in the city of Columbia , '' according to the complaint . `` Our goal is to extract something positive from such a horrific and senseless tragedy and to honor the lives of my sister and her two young sons , '' Weiss said . The wrongful death suit also names Coleman 's father , Ronald , and the Joyce Meyer Ministries , where Coleman worked until shortly after his family was killed , as `` respondents in discovery , '' which means they may be forced to hand over financial documents and information such as Coleman 's personnel file , his work schedule and travel itineraries and the Ministries ' employment policies . In addition , the suit tries to establish a timeline of events before and after the killings , saying the Colemans took the deed to their home in 2005 , but six months ago , ownership was transferred to Christoper Coleman alone . `` Sheri did not voluntarily sign the deed transferring title to the residence to Christopher , '' the document says . Lawyers in the civil suit also allege that in the period between the killings and his arrest , Coleman removed personal property from the home . The suit asks that Coleman and anyone `` acting at his direction '' be forbidden from entering the home again and that he provide a list of items already removed . Coleman remains in jail after a judge denied bond .
