Prosecutors accused Serafini of killing his in-laws in order for he and his wife, Erin Spohr, to gain access to a multi-million dollar inheritance after Serafini's baseball career ended.

Former Major League Baseball pitcher Danny Serafini was convicted Monday of the first-degree murder of his father-in-law and attempted murder of his mother-in-law.

Serafini will remain in custody without bail until his sentencing next month.
