Joseph H. Minoughan of the
Arcadia Police Department was the first officer to arrive at the hospital. Determining that all of the sick children were from the same family, he promptly went to their apartment building to search for and quarantine any potential poison. He found nothing in the apartment indicative of a poison except an insect spray, and did not believe that it could have been the cause of the children's poisoning, so he rushed back to the hospital. Arcadia Police Chief Richard Barnard and
DeSoto County Sheriff Frank Cline were among the next law enforcement officers to examine the apartment. Minoughan came back from the hospital for a second examination of the apartment and found them there. Barnard and Cline went into the unlocked apartment and noticed a very strong smell, but no sign of any poison. Cline believed that the poison might be a
pesticide and went to the shed behind the apartment building to search it; he found no poison there, either. Reporters started flocking to Arcadia to cover the breaking news. Richardson and the law enforcement officers were repeatedly questioned, but did not make any preliminary statements. Frank Shaub, a prosecuting attorney in the area, did respond to reporters and gave them accounts of his investigation of the house.
„Вечер" (Night) from 1967 The next morning, after the death of the last child, Dianne, a two-pound sack of parathion was discovered in the shed. Cline, Barnard, their staffs, and Shaub all agreed that the bag of parathion had not been there the day before, when the premises had been searched five times. They thought that whoever had placed the parathion sack was also probably the person who had poisoned the children. Conflicting reports on how the parathion sack was found were given to law enforcement officers. Minoughan was the first officer to arrive and was told by Bessie Reece, the babysitter, that Charlie Smith, a black resident of Arcadia's Quarters, had discovered the parathion. When Minoughan asked Barnard who called in the discovery to the police station, he was informed that it was an anonymous male caller. The next day Cline and Shaub's local assistant,
John Treadwell, III, told reporters that Richardson had "discussed insurance policies for the children the night before their deaths". It was determined that the insurance salesman,
George Purvis, talked to Richardson just hours before the children were poisoned. According to authorities, Richardson and Purvis gave conflicting stories on the insurance policies. No additional evidence was found for two days. The children's funeral was held on Sunday. Both Richardson and his wife collapsed in sorrow at the service. National news magazines, television, and radio networks covered the funeral. This put Sheriff Cline at the center of nationwide attention. Barnard later told attorney
Mark Lane: "Cline saw the chance to make a big name for himself. He needed to make an arrest real bad." Two days after the funeral Cline charged Richardson with murder in the first degree. However, Police Chief Barnard said, "There just is no case against that man." Treadwell, charged with prosecuting the case if it came to trial, agreed with Barnard. The murder warrants were dropped, but both Richardsons were formally charged with
child neglect. Hayes agreed with Cline and summoned a coroner's inquest "to substantiate evidence already on hand". At the press conference the next day Cline announced that Richardson had five other children who had died under mysterious circumstances in another Florida city and that his motive for this crime was to collect the insurance money on the children, which would total almost $14,000. Judge Hayes said that both Richardson and his wife had taken lie-detector tests and that the results showed that Richardson had knowledge of the poisoning, which indicated he was guilty. The coroner's jury held a hearing on November 2, 1967, at which Judge Hayes said: "We will meet today to instruct Frank Cline to file murder charges against Richardson." This statement carried considerable weight in Arcadia, including with the hand-picked jury, because of Hayes' prominent standing in the county and the fact he had been a judge in Arcadia for more than 31 years. ==Defense==
