A mother whose boyfriend is accused of repeatedly raping her 10-year-old daughter abandoned the girl at her grandparents' home before moving back in with the man, it has emerged. The child, Corinne Gump, and her grandparents were killed in a massive house fire in the early hours of Monday, just hours before Robert Seman, Jr., 46, was to go on trial for allegedly sexually abusing the girl over several years. After the three bodies were found in the  home in Youngstown, Ohio, police went to Seman's home and found Corinne's mother, Lynn Schmidt, WKBN reported. She was taken to the police station to be interviewed but she has not been arrested. Loss: Corinne Gump, 10, and her grandparents were killed in a house fire on Monday - the day her mother's boyfriend was set to go on trial for raping her. Her mother is pictured heading to the police station, right . Left behind: Her mother, Lynn Schmidt, reportedly left the girl with her grandparents and went back to her boyfriend's home, even after she knew he was accused of sexually assaulting her daughter . It has emerged that, following the rape allegations against Seman, Schmidt and her daughter moved in with her parents, Judy and Bill Schmidt, but she eventually headed back to her boyfriend's home. Seman was under electronically-monitored house arrest at the time of the deadly fire but he was taken back into custody on Monday, accused of trying to bribe a witness in the rape case. Investigators said they have found no evidence that the origin of the blaze was suspicious but that they continue to investigate and his trial has been postponed. Corinne Gump and her grandparents, 61-year-old Judy and 63-year-old Bill, who were both deaf, lost their lives in the early-morning blaze after neighbors reported hearing loud explosions. 'It was fully involved,' Fire Chief John O'Neill told The Youngstown Vindicator. 'We had quite a bit of fire in the basement, so that's the likely origin. They had fire all through the house, top to bottom. The floors were giving way almost immediately upon entry.' Accused: Robert Seman, Jr., 46, was back in custody on Monday (pictured) after it emerged he allegedly tried to bribe a witness in the case. He was under house arrest and electronic monitoring at the time of the fire . Taken away: Seman, who allegedly raped the young girl over several years, remains in custody . The three bodies were found on the second floor; all were out of their beds and the way their bodies were positioned looked as if they were trying to get out, Fire Chief John O'Neill told The Vindicator. It is not yet clear if they had smoke detectors in the home. Smoke detectors for the hearing-impaired can send vibrations, sound or light to alert residents. Steve Leland, director of Easter Seals Youngstown Hearing and Speech Center Community Center, told the Vindicator that the local deaf community is mourning the loss of the couple. 'Bill and Judy were always willing to talk to parents who'd just found out they had a deaf child,' he said. 'They would often discuss options for raising a deaf child, talking about their own personal life experiences, being deaf themselves, and raising deaf children.' The couple had three children, two of whom are deaf. William Schmidt was a retired AT&T lineman, while his wife taught deaf people sign language, the publication reported. 'They were very outgoing, very sweet people, always ready to help,' Leland added. Battle: Firefighters pulled the three bodies from the second floor of the home on Monday morning . Destruction: Fire officers said the blaze quickly ripped through the home from bottom to top. But they said there was no evidence that the cause of the fire was suspicious . Questions: Fire Captain Kurt Wright and a State Fire Marshall look into the back of the house on Monday as an investigation continues into the cause of the fire. Neighbors reported hearing explosions . Corinne was a 4th grade student at South Range School, where officials have assembled a crisis team to counsel students and staff affected by the tragedy. Seman, himself a father of a two-year-old, had been accused of abusing Corinne from when she was just four years old until she was eight, WFMJ reported, citing an indictment from a year ago. His trial has been delayed in light of the deaths but no new date has yet been set. Prosecutors are hoping to convince the judge to allow statements the girl made to a social worker and a nurse before her death. He has been charged with four counts of rape and four counts of gross sexual imposition and could face life in prison if convicted. See below for video .
