( CNN ) -- The son of a man who died from intestinal problems says he now wonders whether his father 's wife might have poisoned him . Betty Johnson Neumar is shown at her booking . She is charged with hiring a hit man to kill her husband . Betty Neumar , 76 , was charged by North Carolina authorities last month with one count of solicitation of murder in the July 1986 death of Harold Gentry , one of her five dead spouses since the 1950s . Since the arrest , authorities have launched an investigation into the deaths of her previous husbands , including John Neumar Sr. , her fifth husband . Neumar 's son appeared on `` Nancy Grace '' on Wednesday along with Jay Almond , a news editor with the Stanly News and Press in North Carolina . `` It was n't long after my father married her that he started being sick , '' Neumar said . He said he learned of his father 's death when he read it in a local newspaper . Betty Neumar has not been charged in connection with that death or her other three husbands . `` She has only been charged in one state , '' her attorney Charles Parnell said . `` I want to remind everybody she has only been charged in North Carolina , and obviously , she is presumed to be innocent . There is nothing with the other states because there are no charges at this particular time . '' Here is an edited transcript of the show : . Neumar : You know , actually , murder almost never crossed my mind until the Gentry case came up . In fact , we did not know she was married all this time . We just thought that she was married one time and she was a widow lady who married my father . Well , it was n't long after my father married her that he started being sick and everything . And he was never sick a day in his life [ before then ] . And I figured something was wrong because he put -- such a wedge became between our families that should n't have existed . We were so close . And the longer she was married to him , the less we had to do with him and the more time it seemed like he was sick but she would n't let us know about it . In fact , when he did die , I read about it in the newspaper and did n't even know he was dead . And when I went to the funeral home , she already had him cremated . Grace : Had him cremated ? Neumar : Correct . Grace : Mr. Neumar , what was the cause of death of your father ? Neumar : Well , it 's a complicated thing , and I 'm not very good with these technical terms and all . But from what the doctors say , it was some type of stomach and bowel and , you know , intestine problem and everything , which I 've been told later by some people that the symptoms that he had could be caused by arsenic poisoning . Grace : John , when you first met her , did n't you tell me you believed at that time she was a widow , a one-time widow that married your father ? Neumar : Right . That was correct . We were told that her husband just passed away , and my mother had passed away a couple years before that . And we -- you know , we just figured it was a widow and a widower getting married . Grace : How did she meet your father ? Neumar : A friend of his went up there to where she had a salon to get haircutting . My father , he went to go up there and get his haircut because I think his barber had retired . So he went up there to get his haircut , and that 's where he met her . Grace : And how long after they met did they marry ? Neumar : You know , I 'm bad with time frame , but I 'd say , I think within a year or something like that [ 1989 ] . Grace : Quick courtship . Neumar : Right . ... Jay Almond , news editor : The information I have is based on an investigation that the Stanly County Sheriff 's Office is running , and information there is that the D.A . 's office and the Stanly County sheriff have gathered evidence from witnesses saying that Betty Neumar solicited to commit murder to her husband , Harold . Thomas Harold Gentry was shot to death in Norwood home near the back door inside the home . He was found by friends or family members -- I believe friendly members sent there by his employers . He did n't report to work . ... And [ they ] discover him there dead , and then the investigation there ensues but did not lead to anything enough to press charges against anyone . Grace : .. Jay , what can you tell me about this woman ? What is her background ? Almond : She 's a 76-year-old widow ... and she 's been married four other times . She initially was inviting to family members , but then sort of became more of a wedge in the family and has gone from there , got colder and -- with previous family members .
