On Wednesday, Mark O'Mara, defense attorney to George Zimmerman, said that his witness would be given numbers as identities. O'Mara will submit a list of additional witness to Judge Debra Nelson on Thursday, while keeping their names unknown.

In October, O'Mara presented a list of police involved in the investigation of the murder of Trayvon Martin as well as his client's arrest at the trial.

The police usually provide testimonies for the state. But according to The Hispanic Business, O'Mara will be using this unusual strategy in defending his client who is being charged with second-degree murder of 17-year-old Martin.

The defense claims to currently have between 50-70 witnesses according to the Huffington Post. Zimmerman's legal team submitted a request to delay the trial, which is been set for June 10. O'Mara states that the defense needs additional time to prepare for the case.

Zimmerman was arrested in February for the killing of the 17-year-old, Zimmerman who was armed shot Martin after claiming that he was attacked by the teenager and fired in an act of self-defense. The 28-year-old Zimmerman has maintained the claim to self-defense from the beginning of the case.

In July, the Florida judge set Zimmerman's bail for $1 million, after previously revoking a $150,000 bond, for misleading the court about his finances.

He has been released from jail on bond, but under strict conditions including a round the clock GPS monitoring system.

Court hearing for trial has been set for June 10.
