The bodies of Robert [left], 3, Clara Dietering, [right], 5, and their 68-year-old mother Galina Taypina were discovered by their dad Jason Dietering inside their San Antonio apt on April 27.  They were shot by their mom Karina Dietering, before she killed herself, police said

A Texas mother on April 7 shot to death her two young children and their grandmother  just after losing custody of the children to their father as part of a divorce. She then turned the gun on herself.
The children’s father Jason Dietering was the one who discovered the  bodies of his estranged wife Karina Dietering, 37, along with their two kids, Robert, 3, and Clara, 5, and his 68-year-old mother-in-law Galina Tenzeyevna Taypina had been found inside their San Antonio apartment on April 27, according to police.
Robert and Clara Dietering were recently buried the lawyer for their father, Jason Dietering revealed.
The Jason’s attorney Charles Hardy said his client went for an arranged meet and swap with his ex to hand over custody of the children two days earlier, after he had just won their custody.
However, when he turned up to make the exchange, Karina was a no-show.
Hardy told KSAT.
‘When (Karina) did a no show for the exchange, [Jason] frantically made phone calls. He waited the appropriate time and then asked for welfare checks.’
‘He finally got there on Sunday and again asked for a welfare check but refused to go into the apartment. Monday morning, he looked into the window and found something was amiss,’ Hardy continued. ‘He actually broke into the apartment and found the scene.’

The children’s father Jason Dietering had peeked through a window of the home and contacted police

Police, upon being contacted by the father, went to the home at the Sedona Ranch Apartments.
Responding officers found the victims were laid out in two bedrooms, San Antonio Police Chief William McMannus said.
Authorities said the mother took her own life after shooting the children and her own mom, [the children’s grandmother].
Funerals were held for the children on Saturday. The mother also was buried with the children, as requested by their father, his lawyer says.

‘He said it was not about the mother,’ Hardy told KSAT. ‘It was about the children.’
Hardy explained how the parents initially split and ended up in divorce court.
The children both died of gunshot wounds and their manner of death was classified as homicide by the Medical Examiner’s Office.
Their mother, Karina Klebernova Sornoza Deitering, killed her children and their grandmother, Galina Taypina, 68, before turning the gun on herself
According to Hardy, the family originally from Mississippi, moved after Karina Dietering convinced her husband she was moving to Texas for a job. Sher told Jason the move would be temporary.
However, it turns out there was no job, instead Karina filed for divorce in Texas.
There was a temporary agreement for the children to spend three weeks with their father and three weeks with their mother until a more permanent resolution was reached, Hardy said.
On April 24, the court ruled that Jason would be granted custody of their young children, Clara and Robert, meaning they would live with him full-time in Mississippi.
Three days later the children were found dead along with their mom amd their grandmother. 

Over the course of a year, the couple were able to share custody of the children. However, a judge granted full custody to their father in Mississippi where he lived upon the recommendation of two top psychologists.
The custody swap should have taken place in Orange, Texas. However, Karina never showed up. Instead she ‘killed her [own] mother, these two wonderful children and herself instead of following the court’s order.’
‘Terrible. I can’t even imagine. I can’t even describe it,’ says Hardy, reacting to the murder-suicide found by his client.
There was no previous indication the mother would harm the children, he says.
