At the February 2014 funeral for Brad and Andra Sachs, no one appeared more distraught than their 19-year-old son, Ashton.
“He collapsed on me, crying,” Andra’s childhood friend Ruth Briscoe told PEOPLE.
Less than one month later, Ashton confessed to police that he fatally shot his wealthy parents with a semi automatic rifle as they slept in the family's $2.4 million mansion in San Juan Capistrano, California. He also shot his 8-year-old brother Landon, who was left paralyzed in the rampage.
Asked by police why he did it, Sachs replied simply, "I don't have a reason why. Just a lot of problems."
Sachs pleaded guilty in September 2016.

“She immediately pulled the weapon out and pointed it at Mr. Sheats and wanted to blame him: ‘You made me do this, you’re making me do this,’" Fort Bend County Sheriff Troy Nehls previously told PEOPLE.
But she didn’t shoot Jason. Instead, Sheats chased her daughters, Madison, 17, and Taylor, 22 into the street, killing them before authorities arrived and fatally shot her. As for why she didn’t shoot Jason, Nehls says, “She wanted him to suffer.”

Angered that his wife wanted a divorce, actor Michael Jace, best known for playing police officer Julien Lowe on The Shield, fatally shot his wife in 2014 after she returned to their Los Angeles home after picking up their sons from baseball practice.

The Menendez Brothers
Lyle and Erik Menendez were 21 and 18 in August of 1989 when they fatally shot their wealthy parents in the den of their Beverly Hills mansion. Jose, a 45-year-old Hollywood executive, was shot point-blank in the back of the head. Kitty, 47, was shot 15 times, including once in the face.
The brothers initially blamed the killings on the mob, but then claimed they shot their parents in self-defense after years of sexual abuse by their father. Prosecutors said the brothers were after the couple's $14 million estate.
After two hung juries and a retrial, they were both convicted of first-degree murder.

On the night of Feb. 17, 1970, then-Green Beret Surgeon Jeffrey MacDonald claimed that drug-crazed hippies broke into his family's North Carolina home and killed his pregnant wife and their two daughters.
MacDonald described one of the intruders as a blonde haired woman, wearing a floppy hat and knee-high vinyl boots, carrying a candle and chanting: "Acid is groovy. Kill the pigs."
Authorities didn't believe his story and instead argued that MacDonald killed his family after he became enraged when his youngest daughter wet the bed he shared with his wife.
MacDonald was convicted of the slayings in 1979 and sentenced to three life terms, though he has maintained his innocence ever since.
Last January, his attorneys asked an appeals court to vacate his conviction based on alleged new evidence. A decision is pending.

Gypsy Rose Blanchard
Friends of Dee Dee Blanchard, 48, became panicked when a frightening status was posted on a Facebook page she shared with her 23-year-old daughter Gypsy, who many believed was disabled.
"That bitch is dead!" read the post.
On June 14, 2015, police served a search warrant on her Springfield, Missouri, home and found the ostensibly doting mother stabbed to death and Gypsy missing.
Disturbing secrets about Gypsy and her mother quickly emerged. Dee Dee had claimed her wheelchair-bound daughter was terminally ill and had the intellect of a seven-year-old, but in reality Gypsy had an adult intellect and could walk.
Dee Dee pleaded guilty to her mother's second-degree murder. Her boyfriend, Nick Godejohn, faces trial on charges of murder, as prosecutors alleged the pair hatched a plot to kill her mother.
The case has been cited an example of Munchasen by Proxy, a form of abuse in which a caregiver fabricates an illness or injury to someone in their care to elicit sympathy for themselves.

Michael A. Jones
Police were first called to Michael A. Jones's Kansas City home the day before Thanksgiving for a domestic disturbance call. Once there, they discoverd that Jones' seven-year-old son Adrian had been missing for months. Police came back the next day and found the boy's remains in the family's pigpen.

In May, Jones was sentenced to life in prison. The boy’s stepmother, Heather Jones, pleaded guilty to a charge of first-degree murder and two counts of child abuse. She was sentenced in November.
