Ian Zinderman takes the stand and is being being questioned directly by prosecutor John Skrzynski.

Zinderman identifies Mitchell Young at defendant's table.

Zinderman is a longtime friend of Tucker Cipriano and knew Mitchell Young for two weeks at time of murder.

He has a brush cut and neatly trimmed beard. Young sits stone-faced as the testimony begins. 

Zinderman admits he suffers from complex seizure disorder, causing him difficulty with processing questions.

Witness also admits he suffers from Attention Deficit Disorder. 

He has been granted immunity from prosecution in return for his testimony.

Zinderman said he first spoke to police on April 16, 2012, the morning after the attack at Cipriano home. 

In final weeks of March, he hung out at home of James and Keontay Williams, drinking, smoking marijuana, Spice (K-2), and socializing.  

Mitchell Young also known as "Roderick." 

He was in a group with Zinderman and Tucker Cipriano. 

At the end of April, Young and Tucker approached Zinderman and asked him if he wanted to make a little bit of money. 

Zinderman said a plan was discussed to go off and do a crime, to kill a family. But it wasn't specified as to which family.

"Tucker wanted to get out of state. He violated his probation and wanted to get out.  He didn't want to go back to jail," Zinderman said.

They needed a car. 

Prosecutor: Was that going to be part of the job?

Zinderman: Yeah.

They felt they could get roughly $3,000.

They offered Zinderman 1/3 share.
