Hillsborough County Sheriff Chad Chronister says he believes more than one person killed Don Lewis

A Florida sheriff says he believes cat conservationist Carole Baskin’s second husband Don Lewis was likely killed and more than one person was behind what could be a murder-for-hire plot.

Lewis' disappearance was the big mystery raised in Netflix’s series Tiger King: Murder Mayhem And Madness that has become an online sensation.

Baskin and Lewis were married in 1991 until he vanished without a trace in August 1997.

Lewis, a real estate businessman, was declared legally dead in 2002, leaving behind $5million in assets.

Hillsborough County Sheriff Chad Chronister says he believes Lewis was likely killed and he's suspicious of Baskin and believes other people were in on the murder plot.

'I’m extremely suspicious but not just of her, of this whole circle here,' Chronister said to TMZ.

'I don’t want to allude to the fact or insinuate that she’s our person of interest we’re focusing on. I’m not comfortable saying that yet,' he added.

'There’s normally not one person that commits a homicide, it’s always a couple people. This had to be extremely planned out, this had to be well thought out. There’s someone else involved in this. There’s someone who was paid to do it, there’s someone who helped do it,' he said.

He pleaded with whoever was possibly involved with the case, or knowledgeable about it, to come forward.

'I hoping that person wants to come and get this off their chest and help law enforcement do the right thing,' he said.

When it comes to perhaps cutting a deal with authorities, Sheriff Chronister said, 'every deal is on the table right now. Help us solve this case.'

Chronister speaks about the case in a special entitled 'TMZ Investigates, Tiger King: What Really Went Down?' to air on Fox Monday night at 9pm ET/8pm CT.
