( CNN ) For more than four days , police say , a 21-year-old quadriplegic with cerebral palsy was left lying in the woods of Philadelphia 's Cobbs Creek Park with only a blanket and a Bible . The person responsible is the man 's mother , who on Sunday faced a host of charges after allegedly abandoning her son and catching a bus to Maryland to see her boyfriend , said Philadelphia police Lt. John Walker . Low temperatures reached the mid-30s during the week , and rain was reported in the area Wednesday and Thursday . The man is unable to communicate how he came to be in the park , but Walker told reporters that the man 's mother , whom he did not identify for CNN , left him there Monday morning . `` Sometime at 11 a.m. , the mother went to visit her boyfriend down in Maryland , over in Montgomery County , and we believe she placed the child into Cobbs Creeks Park , '' Walker said at a news conference . Walker told CNN the man was transported to Presbyterian Hospital , but CNN affiliates reported he was being treated at The Children 's Hospital of Philadelphia . He suffered eye problems , dehydration , malnutrition and a cut to the back that has raised infection concerns , the lieutenant told reporters . `` This kid 's obviously a fighter , '' Walker said during a Saturday news conference . `` It 's just unbelievable how we found him out there last night . To see that kid laying there , it 's heartbreaking to see another human , especially a mother , can treat someone like that . '' Officials at Philadelphia 's School of the Future , which the man attends , became concerned when he did n't show up for classes and tried to contact his mother but eventually reached an aunt , CNN affiliate WPVI reported . When police tracked down the mother , she told them her son was with her , Walker said . `` She indicated to both family members and the police officers that the child was with her down with her boyfriend in Maryland , '' he said . The boyfriend was not aware of what happened , Walker told CNN affiliate KYW-TV . The mother now stands charged with aggravated assault , simple assault , reckless endangerment of another person , neglect of a care-dependent person , unlawful restraint , kidnapping and false imprisonment , the station reported . Walker told reporters she bore `` clear criminal liability in this case . '' Maryland police took her into custody on Sunday , and she will face the charges in Philadelphia following an extradition hearing , WPVI reported . There was no reason for the man to suffer , Walker told philly.com , because the mother had sisters willing to take care of him . Two of his aunts , who have tried to obtain guardianship of him , were staying with him at the hospital , police told the website . The mother has another child , a 16-year-old , who is also being taken care of by family members , WPVI reported . The mother 's arrest was only the beginning of the investigation , Walker told reporters . Authorities are interested in learning more about `` how this kid was cared for , and what actions were taken and providing of services by different agencies .
