“Two and a Half Men” star ANGUS T. JONES has a shocking family se­cret– his uncle is serving time in prison for murder!

In 1995, Angus’ uncle Eric Eugene Claypool was convicted of shooting a man he claimed sexually abused him as a teenager. Police documents obtained by The ENQUIRER reveal that on Nov. 16, 1994, Claypool stole a .357-mag­num from 31-year-old Jay Harlan and shot him in the back of the head. Claypool, now 38, was sen­tenced to 99 years and is behind bars at Telford Prison in Texas.

This isn’t the only time 19-year-old Angus has been embarrassed by his fam­ily’s run-ins with the law. His mom, Carey Jones – Claypool’s sister – was ar­rested in 1992 for drunkenly rip­ping the meter out of a taxi and then punch­ing a cop in the face on the way to jail. And five years later, she was arrested on a bizarre burglary charge after a woman woke up at 4 a.m. to find Carey in her living room – wearing a pair of shorts owned by the woman’s live-in boyfriend! That c a s e w a s later dis­missed.

Angus’s dad, Kelly, has also en­countered legal troubles. He was arrested in 1986 for possession of marijuana and carrying an unli­censed .45-caliber handgun after he caused a disturbance outside an Austin, Texas, bar.

And in 1997, Carey had Kelly arrested after he allegedly pulled her out of a car and pushed her to the ground.

Despite the family turmoil, Angus has entertained millions of viewers playing Jon Cryer’s slacker son on the hit sitcom since its 2003 debut. And in 2010, he be­came the highest paid child actor on TV when he signed a contract that amounted to a whopping $300,000 per episode.

“Angus was mortified when his parents’ shady pasts were uncov­ered and fans found out that they’ve both been arrested mul­tiple times,” a family friend told The ENQUIRER.

“And he’s badly embarrassed to have an uncle who’s sitting in prison for murdering someone, especially a murder that occurred under such shocking circum-stances.

“Angus knows you can’t pick your family, and has managed to be a huge success in spite of their criminal behavior.”
