TV exec killed her disabled sister so she didn't have to take care of her. She will be free from prison in under a decade.

A former TV producer grew tired of taking care of her deaf and blind sister, so she drugged her and put in her a room filled with carbon dioxide.

She will be free from prison in under 10 years.

In 2018, Jill Blackstone was arrested on a murder warrant for killing her sister, Wendy, in 2015. Jill Blackstone is a former TV executive whose work included “The Jerry Springer Show” and “Family Court With Judge Penny,” according to the Los Angeles Daily News.

Initially, Jill Blackstone was arrested on suspicion of her sister’s death soon after the killing. But she was released after prosecutors asked police for more evidence. She was arrested again years later.

Wendy died from smoke inhalation and overdose of a sedative, according to the Associated Press.

Investigators said Blackstone drugged her sister, forged a suicide note and put her in a garage with a lit charcoal grill. Two of her three pet dogs were also in the garage. Wendy was deaf and partially blind.

Police in the Los Angeles areas said they found notes that warned people to enter the garage carefully and “both parties have do-not-resuscitate orders,” according to the AP.

Blackstone’s motivation was frustration at the emotional and financial toll of taking care of Wendy, investigators said.

When she was arrested the second time, police said they conducted an investigation that included numerous interviews and additional forensic work.

“It’s a murder case; we continue to work on murder cases until they are solved,” LAPD Det. Dave Peteque said, according to the LA Daily News. “It doesn’t matter how long it takes.”

Last month, Blackstone was sentenced to eight years in prison after pleading no contest to voluntary manslaughter and animal cruelty. She was initially charged with murder and faced life in prison.
