One of America's most prolific serial killers and sex offenders made a stunning admission as he was being taken to jail, a former detective who worked on the case has revealed.

John Wayne Gacy, who was executed in 1994, is the subject of a new true-crime documentary series on streaming platform Peacock called John Wayne Gacy: Devil in Disguise.

Rafael Tovar, a former Des Plaines Police detective who was involved in exhuming the remains of 26 of Gacy's victims from the crawl space in his house, participated in the documentary series. Speaking to Fox News, Mr Tovar recalled a conversation he had with Gacy on their way to Cook County Jail.

"I flat out asked him if there were more victims," he said. "I said, 'How many people did you really kill?' And he said, 'Well, I told my lawyer this number – 30-something. And you guys got about 32, 33 or 34. But 45 sounds like a good number.'"

Meanwhile, Donald Trump has slammed Joe Biden's first ever media conference, saying the President was thrown "soft balls" when he took questions about the conditions faced by migrants at the Mexican border.

"They were strange questions and they were asked in an interesting way. They were thrown like soft balls," Mr Trump said. "They (the migrants) are living in very dangerous conditions. There's no testing for COVID-19 … what's going on is absolutely insane," he said.
