This is the chilling message a mother wrote on Facebook a day after allegedly abandoning her quadriplegic 21-year-old son in the Pennsylvania woods with just a blanket and a bible. 'I'm so happy,' Nyia Parler, 41, commented under a new picture of her cuddling her boyfriend on Tuesday. Just 24 hours earlier, police say she wheeled her care-dependent son into a park near their home in south west Philadelphia and left him there, before going to stay with her partner in Maryland. Relatives, who had been contacted by the boy's school when he didn't turn up to class on Tuesday, commented on Parler's picture, 'nyia call me asap,' and 'How the hell you happy?!? Call me!' On Sunday police said that Parler will be arrested as soon as she is released from hospital herself. Parler was admitted to a Maryland facility on Sunday for an 'undisclosed condition' and faces charges including aggravated assault, reckless endangering, neglect of a care-dependent person, kidnapping, unlawful restraint and false imprisonment, according to police in Pennsylvania. 'When her treatment is completed, we will take her to court and she can either waive or fight extradition,' Capt. Paul Starks of the Montgomery County, Maryland, police said in a statement. Chilling: This is the message Nyia Parler wrote on Facebook hours after she allegedly left her quadriplegic son alone in woodland with just a blanket and a bible. Relatives contacted by the boy's school frantically replied . Charged: Parler (right) was detained in Maryland on Saturday night, charged with assault and neglect. Police say she left her son on Monday to visit her boyfriend John Ferguson (left) in Montgomery County, Maryland . Horrific: The quadriplegic man was found here on the floor of a secluded woodland outside Philadelphia with this Bible and this blanket, 10 feet from his wheelchair. He'd allegedly been left there by his mother five days earlier . Parler left her son — who also has cerebral palsy — lying in leaves and covered with a blanket next to a wheelchair while she left town on a romantic getaway with her new boyfriend, John Ferguson, police said. He was found on Friday night near Cobbs Creek Park. Police believe he had been there for five days and the last time he and his mother were seen together was on Easter Sunday. She then boarded a bus to bisit Ferguson in Maryland, said Lt. John Walker of the Southwest Detectives Division. Walker said the victim was found around the corner from their home, and he described the scenario authorities believe to have taken place: 'She pushes him about 150 yards from the highway into the wooded area, takes him out of wheelchair, lays him on the ground, puts a blanket over him and leaves a Bible with him, and then just walks away.' During the period he was exposed to the elements, the young man was 'completely defenseless' in an area with wild animals, with no water and in cold, damp weather, Walker said. 'It's only by the grace of God that he survived this. Amazing,' he said. Reports claim relatives have been trying to obtain guardianship of the boy from Parler (pictured) for years . Contacted in Maryland after the young man's school became concerned about her absence, the victim's mother told relatives and authorities that he was with her, Walker said. 'Obviously her statements made during the week were not truthful,' he said. Her boyfriend, however, assumed other relatives were caring for the young man and 'was in shock when he learned what happened,' Walker said. A 16-year-old son also residing with the family is now in the care of other family relatives, Walker added. Walker said the son was hospitalized with dehydration, malnutrition, a deep cut on his back that caused concern about potential infection and possible eye injuries, but he appeared to be improving. 'He seemed to be a little happier yesterday,' Walker said. 'You could tell he knew his family was around and felt more comfortable. The 21-year-old, who is non-verbal and suffers from cerebral palsy, is now in Philadelphia Children's Hospital with his aunts, where he is being treated for dehydration and cuts to his back and eyes. Officials told NBC Philadelphia her son would have died if he hadn't been spotted by people walking along a nearby street. 'This kid is obviously a fighter. It's just unbelievable how we found him last night. It's just heartbreaking to see how another human, especially a mother, could treat him like that,' Lt. Walker of Philadelphia Police told ABC. Abandoned: A passerby noticed the 21-year-old here in a wooded Philadelphia park . The son was hospitalized with dehydration, malnutrition, a cut to his back and eye injuries. According to Philly.com two of his aunts, who are with him in hospital, have been trying to obtain guardianship for years. A neighbor, who declined to be identified, told DailyMail.com: 'She used to push him out to the school bus in his wheelchair, she seemed to care for him. Whenever I saw him, I saw her.' Another, who also wished to remain anonymous, said: 'I would see them outside together in the summer when he got home from school. Nothing looked wrong, I didn't suspect anything.' Walker said the son was exposed to the elements and other dangers. 'A lot of things could have happened out there,' he said. 'Obviously he's in the middle of a wooded area. You have wild animals there ... this kid could not defend himself. He does not function at all.' Walker added : 'What we've learned so far is that the 21-year-old child lives with his mother, completely dependent on mom as a result of his condition. 'She also has a 16-year-old son who is staying with other family members. 'We know she left for Maryland on Monday to go see her boyfriend on a bus.'
