Police said they still don't have a motive for the massacre

Aldridge's computer was found torched in a burn barrel outside his home and his hard drive was unrecoverable

They also found a .22-caliber rifle and pistol, several knives and extra magazines and ammunition in the car where Aldridge's body was found

Joseph Aldridge, 36, shot dead seven of his relatives and neighbors in Tyrone, Missouri before killing himself on February 26

A blood-stained .45 caliber handgun, a barrel with a torched computer inside, a red pickup truck with a shattered window on the driver's side.

These are just some of the items police discovered last February after a convicted felon went on a rampage in his small Missouri town, killing four of his relatives and three of his neighbors.

Months before the massacres in Charleston, South Carolina and Roseburg, Oregon captivated the nation's attention, it was the tiny town of Tyrone that Joseph Aldridge turned into a headline.

One neighbor told Daily Mail Online shortly after the shocking murders that Aldridge, 36, had probably killed '10 per cent of the population' in a town estimated to have 50 residents.

It was in Aldridge's red pickup truck that they discovered the pistol he used to shoot his victims.

Also inside were a .22-caliber rifle and pistol, several knives, and extra magazines and ammunition, according to the St. Louis Post-Dispatch.

Police still aren't sure how Aldridge, who served 21 months in federal prison after he pleaded guilty to possessing drugs and a firearm in 2008, was able to obtain one of his guns.

The pistol had been purchased by Aldridge's mother a year earlier. But the .45-caliber gun had it's serial number scratched off, and police believe Aldridge purchased the rifle from a private seller.

But what police do know is that Aldridge went to the homes of his victims, all within a three-mile radius of each other, on February 26 and began to pick them off, one by one.

Aldridge used this .45-caliber pistol to shoot dead his victims before committing suicide. Police still do not know how Aldridge, a convicted felon who served 21 months for possession charges, obtained it

Aldridge's body was discovered that night by police in his red pickup truck

Police still have not figured out a concrete motive for Aldridge's massacre

The first 911 call was made at 10.08pm by 15-year-old Mica Aldridge, who ran to her neighbor's house barefoot in the snow after she heard the gunfire.

Aldridge had just shot her father Garold 'Dee' Aldridge, 52, and his 47-year-old wife Julie Ann. Garold was his first cousin.

He would also shoot his cousin Harold Wayne 'Weasel' Aldridge, 50, and his 48-year-old wife Janell.

At some point during the rampage Aldridge also shot his neighbors Carey Shriver, 46, and his wife Valirea, 44, murdering them both in their bedroom.

Their 13-year-old son John was sleeping in another room and unharmed.

Police believe Aldridge went to Carey Shriver's parents home last, convincing them to let him in their home by revealing his mother had just died.

Martha Shriver, 67, said her husband Darrell, 68, asked Aldridge what they could do help.

She said Aldridge started shooting after telling them, 'You deserve this'.

Darrell Shriver was killed. Martha, who was shot multiple times and remains in a wheelchair today, dragged herself through two rooms to reach a phone and call 911 at 10.36pm.

Police found Aldridge later that night, 25 miles away from the town on a gravel road connected to an old friend from high school who hadn't spoken to him in a year.

Aldridge was inside the red pickup truck, dead from a self-inflicted gunshot to the head.

Eight months after that horrific night, police have yet to uncover Aldridge's motives - though there have been plenty of theories.

A resident of the nearby town Summersville told Daily Mail Online that Aldridge and Shriver families had been feuding for years.

The Shrivers owned 1,200 acres in Texas County, with business including construction, cattle and a cabinet making shop that employed many people in the town - including, at one point, Aldridge.

Martha Shriver told police she had never had any problems with the man who was once her science student.

John Shriver speculated that Aldridge may have been set-off after he asked his cousin Darrell for a job and was turned down, he told The Associated Press.

It was John who found the dead bodies of Carey and Valirea Shriver.

Others have said there was tension between the Aldridge cousins.

Aldridge's brother Lyndell, 53, had recently been in a physical fight with Dee and Weasel Aldridge, according to police.

Martha and Darrell Shriver were also attacked after Aldridge convinced them to let him inside, telling the couple (pictured here with their grandchildren) that his mother had passed away

And some have pointed to the death of Aldridge's mother Alice, who passed away from cancer only 30 to 36 hours before her son's deadly rampage. Her body was found by police.

Aldridge lived with his mother and Lyndell said he had become increasingly quiet in the weeks before her death, even shutting himself in his room when his brother came by the house to visit.

Police may never know. Aldridge's computer was found torched in a burn barrel in the house's backyard. The hard drive could not be restored.

Meanwhile, Tyrone continues to reel from the massacre.

The Shrivers' successful cabinet shop has closed its doors, as has a number of the family's other businesses.

The victims' houses remain unoccupied and their surviving children have moved away from the town, as has Martha Shriver.

'I don't think you really ever get over it,' she said. 'It just takes your whole life away.'
