Testimony underway in Livingston trial

KALAMAZOO, Mich. (NEWSCHANNEL 3) - Testimony is underway in the high profile murder trial of a Kalamazoo businessman.

Investigators say Bob Medema was beaten to death inside his home back in August.

He owned The Emporium antiques shop in downtown Kalamazoo.

Antonio Livingston and John Aguilar are charged with killing Medema, but Livingston is the first to stand trial.

The morning began with opening statements. While the prosecution, of course, argued that Livingston was guilty, the defense claims that he merely thought he was helping John Aguilar pick up something from a garage sale.

They argued that it was only after Livingston saw Aguilar beat and kill Medema that he realized what was going on.

"The mere presence of Mr. Livingston while this incident occurred does not make him guilty," defense attorney Susan Eifler said. "(it) does make him an aider and abettor."

From there, we heard from witnesses, including Medema's longtime friend Dann Klaassen, who saw Medema's body lying on the kitchen floor.

The prosecution also showed photos of both the shoes and the ski mask found nearby.

Through all the photos and testimony, Livingston sat motionless.

The other suspect, John Aguilar, is set to stand trial in April.
