Ohio man, 81, who shot dead Uber driver tricked into going to his house by scammers reveals caller demanded $12k and said they'd KILL his family if he didn't hand cash to her: Cops trace suspect's burner phone to Canada

An Ohio man who shot an Uber driver has revealed the chilling scammer threats which drove him to kill the innocent mother who turned up at his home. 

William Brock, 81, gunned down Lo-Letha Toland-Hall, 61, on March 25 in the rural village of South Charleston, located between Columbus and Cincinnati.

Chilling 911 audio followed the moment Ohio cops discovered Toland-Hall dying on his driveway - and now a call from Brock has revealed why he pulled the trigger. 

Brock explained to police on the phone that he had been receiving calls from an unknown man who threatened to murder him if he didn't pay $12,000. 

'The guy on the phone that's been trying to get money out of me... he was telling me he's going to kill me and the family,' Brock can be heard telling cops in the audio before explaining that he had shot Toland-Hall.

Police believe the same fraudsters called Toland-Hall's Uber to Brock's home to 'pick up a package' full of the money they demanded.  

The mother-to-one from Columbus became the oblivious victim of a twisted set-up when she arrived at his property and he demanded to know who sent her before pulling the trigger. 

Ohio cops have since traced the scam calls to a mobile device in Canada - but it is believed to be a burner phone. 

They told Good Morning America they picked up a call to Brock's home which came from the scammer, and arranged to meet him, but he never turned up. 

On the day of the shooting, the scammer called Brock telling him a relative was in jail. 

They demanded money from him, then placed an order via Uber for someone to collect a package from his house, officials believe. 

Dashcam footage from Toland-Hall's cab released by Clark County Sheriff's Office shows what happened when she turned up at the property on Clifton Road. 

Toland-Hall emerged from her vehicle and approached the front door - and Brock whipped out a pistol while demanding she identify who had sent her. 

Unaware of the scam the elderly resident was facing, Toland-Hall said: 'Sir, I'm here to pick up a package'. 

Brock has been charged with murder after he admitted to shooting an Uber driver who'd been tricked by a scammer to pick up a package at the man's home

Lo-Letha Hall, 61, was an Uber driver who had been called on a job to pick up a parcel from William Brock's home. Brock, who had been receiving scam calls moments before, believed Hall was there to take his money, according to officials 

One of the people he suspected was scamming him and threatening him messaged Uber delivery driver Letha Hall (pictured left), 61, to tell him to pick up a package at Brock's home 

Believing she was part of the set-up, Brock retorted: 'Yeah, I know what you're after'.  

Brock shot Toland-Hall at least three times. She suffered wounds to her upper left side of her torso, left thigh, inside of her left knee and the center mass of her sternum.

Toland-Hall tried to get back to her car as Brock shot her. She can also be heard screaming in pain while Brock threatened to 'shoot the other leg.' 

Brock said she attacked him after he fired the first shot by slamming his head into her car door. 

He shot her again as she tried to escape, because according to him he believed she was about to retrieve a weapon of her own. 

'I was threatened that she was going to come and kill me,' Brock told police on the phone after the incident. 

DailyMail.com also obtained audio of the 911 call he made after shooting. 

A female call handler reads Brock's address at Clifton Road before saying: 'Getting a report of a female that has been shot... a black female laying in the driveway.'

'She's been shot in the leg, possibly somewhere else as well,' the call handler adds. 

'It sounded like the caller shot the female,' she added. 'She was shot in the leg and shoulder.' 

Toland-Hall was taken to a local hospital but died while undergoing surgery, authorities said.

Hall showed up at Brock's home and according to police, 'made no threats or assaults' toward him and just asked about the package. Fearing she was going to hurt him, Brock whipped out a gun and demanded she identify who had sent her

Uber has said it is supporting the police investigation into the tragedy.

'This is a horrific tragedy and our hearts continue to be with Lo-Letha's loved ones as they grieve,' the ride-hailing app said in a statement. 

'We have been in contact with law enforcement and remain committed to supporting their investigation.'

Brock has been charged with murder since he didn't call 911 until after the shooting, and because there was 'no active threat presented by Ms. Hall at any time during the encounter' according to police. 

He posted a $200,000 bond but could face further charges after the incident is investigated further.
