-LRB- CNN -RRB- -- Renee Pernice , a 35-year-old mother of two young children , vanished from her home in Kansas City , Missouri , shortly after New Year 's this year . She has n't been heard from since . Renee Pernice is pictured here with her two sons and husband , Shon . Police believe foul play is involved , yet they have not found her body . No one has been arrested in the case . Police have not named her husband , Shon Pernice , as a person of interest or a suspect in the case . However , `` he 's the last known person to see her alive , '' said Doug Niemeier , a sergeant with the Kansas City Police Department . Six months after Renee Pernice disappeared , police say they still have questions about her husband in the days after her disappearance , including why he allegedly accessed a local fire department 's hazardous materials building around 4:30 a.m. January 3 . `` It should be noted that multiple types of cleaners , solvents and cleaning supplies are stored at Station # 5 , '' a police affidavit says . Attorneys for Shon Pernice declined to comment for this story . Police and family say Renee was pursuing a divorce around the time she disappeared . A local firefighter , Shon Pernice has said he was not involved in her disappearance . He told a local activist in March that `` I did n't harm my wife one bit . Not at all . '' In that interview , one of the few in which he 's referenced his wife 's disappearance , he added , `` It 's gut-wrenching thinking that either she 's got a rich-ass doctor boyfriend somewhere and she 's happy , or she 's dead . '' Since his wife disappeared , Shon Pernice has been arrested twice on unrelated charges : once for allegedly stealing a neighbor 's gun and another time for disturbing the peace in an incident with that same neighbor this past July Fourth weekend . `` As everybody knows , my wife has been missing since January 2 , '' he told CNN affiliate KCTV5 . `` This is what it stems from . Basically what the media ... has portrayed of me -- of the whole situation . There 's a lot of people that do n't like me . '' The couple 's two sons , ages 6 and 9 , remain in the care of the father , although Renee Pernice 's mother has sought custody of them . `` There is a lot that just is n't right , '' said Rick Pretz , the missing woman 's father . `` It 's not a stable environment for the children . '' Renee Pernice was known for being a caring mother , a talented nurse at St. Luke 's Hospital and a gentle animal lover always surrounded by dogs . Neighbors say they last saw her in her backyard with her dogs the morning of Friday , January 2 , 2009 . When police searched the home , they say they found her purse , coat and other items still in the house . Her car was in the garage . Police say her cell phone was missing from the house . A homeless man found the phone in grass about 15 miles from her home , in an area Renee Pernice was not known to frequent , police say . It was found around midnight January 3 , the affidavit says . Since then , police and volunteer teams have searched the area extensively , but they have found nothing . `` Family members and common friends of both Shon and Renee told police that Renee was not the kind of mother who would separate herself from her children for any reason , '' the affidavit says . `` Family members advised that finding Renee 's purse at the residence was highly unusual as she never went anywhere without her purse . '' According to the affidavit , investigators watched Shon Pernice drive away from the home with his wife 's dog and drop it off at a park a few days after he reported his wife missing . The affidavit also alleges that a drop of blood was found in the garage . However , authorities have not released whether it matched Renee Pernice or her husband . According to Renee Pernice 's family , she was not the kind of person to take off on her own without letting her family know where she was . `` I spoke to her just the night before at 7 p.m. on the phone , '' her father told CNN . `` She would never leave her two sons like this . '' The family is offering a $ 25,000 reward for any information leading to the whereabouts of Renee Pernice . A white truck that could be related to her disappearance was captured on a surveillance tape in the area where her cell phone was found , and police have released a photo of it . Anyone who may have lent such a truck at the time the surveillance image was taken is being asked to come forward . Renee Pernice is white , stands 5 feet , 7 inches tall , and has brown hair and blue eyes . Anyone with information is urged to call the Kansas City Police Department at 1-816-474-TIPS .
