WASHINGTON ( CNN ) -- Washington police told the mother of slain congressional intern Chandra Levy that an arrest is imminent in her daughter 's 2001 death , Susan Levy told CNN on Saturday . Washington intern Chandra Levy 's body was found a year after she disappeared in 2001 . `` I got a call from the Washington police department , just to give me a heads up that there 's a warrant out for the arrest , '' Levy said . Police Chief Cathy Lanier of the Metropolitan Police Department did not reveal the suspect 's name when she contacted the parents on Friday , Levy said . She said police told her they have `` enough evidence to convict somebody . '' A source close to the investigation told CNN the suspect was Ingmar Guandique , who is serving a 10-year prison sentence for two assaults in Washington 's Rock Creek Park that occurred around the time of Levy 's disappearance . Levy 's remains were found in the park . View a timeline of her disappearance » . The source would not speak on the record because the investigation is ongoing and the arrest warrant had not been finalized . A California native working as an intern for the Federal Bureau of Prisons , Levy , 24 , disappeared May 1 , 2001 . Her remains were found in May 2002 by a man walking his dog in a remote area of the park . The source said authorities are working to finalize the arrest warrant . Asked about reports that Guandique , a laborer from El Salvador , told a fellow inmate he killed Levy , the source said Guandique `` was running his mouth . '' Guandique has been imprisoned at the Federal Correctional Institution - Victorville , a medium-security facility north of San Bernardino , California , an official there confirmed to CNN on Saturday .

Guandique was mentioned last year in a Washington Post article about the killing . `` It 's a bittersweet situation for me as the mother of a daughter who is no longer here . I want justice . I want to know that the person who did it is in jail and will not do it to anybody else , '' Levy said . `` Every day the elephant is there . Every day you get a knot in your stomach . It does n't go away . It 's a life sentence for the families and relatives that miss their loved ones . We have a life sentence of hurt . '' Referring to the impending arrest , Chandra 's father told CNN affiliate KXTV that Lanier did n't say when an announcement would be made , but `` she said it would be really soon . '' `` She did n't say the name yet , but we think we know who it is . I do n't want to say until it 's official , though , '' the father said . The search for Levy and massive publicity that accompanied it stemmed largely from her connection to Rep. Gary Condit , D-California . Condit and Levy , who was from Condit 's district , had an affair , and police questioned Condit many times in connection with her disappearance . Police never named Condit as a suspect . Condit , a member of Congress since 1989 , lost the 2002 Democratic primary and left office at the end of his term . He later reportedly moved to Arizona . `` For the Levy family , we are glad they are finally getting the answers they deserve . For my family , I am glad that their years of standing together in the face of such adversity have finally led to the truth , '' Condit told WJLA on Saturday . Condit 's lawyer , Abbe Lowell , blamed police and media attention on Condit for delays in the arrest . Police never named him as a suspect . `` It is a tragedy that the police and media obsession with former Congressman Condit delayed this result for eight years , and caused needless pain and harm to the families involved , '' Lowell said . `` This should give the Levys the answer and closure they deserve , and remove the unfair cloud that has hung over the Condits for too long . '' CNN 's Carol Cratty , Karen Zuker , Justine Redman and Rachel Streitfeld contributed to this report .
