A killer who [email protected] a mum and then kill her and her two children has been executed in Missouri via lethal injection.
Mark Christeson, 37, was sent to death row in 1998 for the murders of of Susan Brouk, her 12-year-old daughter, Adrian, and 9-year-old son Kyle.
He broke into the family home with his cousin before
committing the grisly crime.
Christeson, who has the IQ of an 11-year-old, was prounced dead at 7.05pm local time, according to the Missouri Department of Corrections.

The pair drove the family to a pond where Christeson cut the throats of the mother and son and threw them into the water.
They then suffocated the daughter and threw her into the pond.
Carter testified against Christeson at trial and received a sentence of life in prison, according to the St. Louis Post-Dispatch.
The U.S. Supreme Court temporarily halted Christeson's execution in 2014 after his legal team argued his previous attorneys had failed to meet a key deadline for filing court papers in 2005 and had refused to cooperate when the mistake came to light.
In January 2015, the Supreme Court threw out an appeals court ruling, denying Christeson another chance for his case to be heard.
His current attorney, Jennifer Merrigan, petitioned the Supreme Court for another stay of execution on Monday.
The request was denied on Tuesday.
Christeson was also denied a clemency request by Missouri Governor Eric Greitens on Tuesday evening.
"Mark was 18 at the time of his crime and has an IQ of 74," Merrigan said by email on Monday.
"His execution may be unconstitutional, but the courts keep trying to rush him to the death chamber instead of giving him a fair opportunity in court."
Following Christeson's execution, there are 24 men on death row in Missouri, according to the Missouri Department of Corrections.
Last year, the state executed Earl Forrest, who was convicted of killing three people, including a sheriff's deputy, in a dispute over drugs in December 2002.
