Prosecutors say the couple carried out the plan in November, when Leinheiser shot 46-year-old Marc Rubin in his Abington home. According to wire reports, Rubin and Leinheiser left Marc Rubin's body in an apartment for about a week before disposing of it.
Rubin's body was found days later, dumped in a secluded area in Hamilton Township.
Police were able to link Leinheiser to the murder weapon while investigating a separate, accidental shooting at a local hotel.
A third suspect, Daniel Dougherty is accused of helping to dispose of Mr. Rubin's body. He has been jailed on a number of charges.
Both Christina Rubin and Jeffrey Leinheiser are jailed without bail.
