Jury deliberating fate of man accused of killing Metra officer

MARKHAM, Ill. (WLS) -- There's been a full day of deliberations and no verdict yet in the trial of Jemetric Nicholson, accused of killing Metra Police Officer Thomas Cook.

The jury has been deliberating for about 13 hours, and there are indications they may be deadlocked.

The jurors sent a note to the judge asking several questions about if the defendant would be guilty if he was simply withholding knowledge of the crime.

Prosecutors say that it was Nicholson who fired the shot that killed Officer Cook in 2006. Nicholson testified last week and jurors also saw video of his interrogation by police.

They asked to see parts of that video again on Wednesday, and also sent a note to the judge saying that they were unable to come to an agreement. The judge told them to keep working on it.

Cook was a three-year veteran officer with the Metra police and before that, was an officer with the department in Riverdale, and he was an army veteran. He was 43 years old when he was killed.

Nicholson is currently serving a long sentence for other unrelated crimes.

Officer Cook's family says that even though he is likely to be in prison for the rest of his life, that is little consolation. They would like to have answers in this case so that Cook can rest in peace.
