A third suspect in what investigators call a murder-for-hire plot orchestrated by the victim's son has been arrested.

21-year-old Johnny Roman Leon III was taken into custody Wednesday at Aspen Heights in College Station for his role in the shooting death of Ted Shaughnessy on March 2, according to the Travis County Sheriff's Office.

Leon is charged with criminal solicitation of capital murder.

A spokesperson for the Travis County Sheriff's office told KBTX even though no one has been named as the shooter, Leon's role as the gunman is a "distinct possibility."

Shaughnessy, an Austin jewelry store owner, died in the attack. His wife, Corey, was not injured.

Shaughnessy's son, Nicolas, is alleged to have conspired with Leon to kill Nicolas' parents in order to receive a $2 million life insurance payout.

Investigators say Leon was identified after investigators poured through surveillance video at Nicolas' home in the 2300 block of Cottage Lane in College Station.

Nicolas and his wife, Jaclyn Edison, said they were at the home when Shaughnessy was killed.

Nicolas Shaughnessy is currently in jail on a $3,000,000 bond according to Travis County jail records.

Last month, Jaclyn Edison's $1 million bond was reduced to $250,000, according to the Travis County District Attorney's Office. She has since bonded out of jail. Edison is a student at Texas A&M University.

Shaughnessy and Edison are both charged with soliciting to commit capital murder, a first-degree felony.
