He witnessed the murder but he had nothing to do with the killing of Odin Lloyd. This was the closing argument of former NFL player Aaron Hernandez's lawyer before a jury who will decide the fate of the ex-Patriot star accused of killing the boyfriend of his fiancee's sister.

Boston Herald said the jury has not yet decided on a verdict but is expected to have one on Wednesday.

"He was a 23-year-old kid who witnessed something. A shocking killing. Committed by someone he knew. He didn't know what to do. He just put one foot in front of the other," defense lawyer James Sultan was quoted by Boston Herald as saying during his 90-minute closing argument.

Sultan also stated that either Ernest Wallace or Carlos Ortiz, Hernandez's co-defendants, could have killed Lloyd. The victim's body was found in a North Attleboro industrial park in the morning of June 17, 2013, Boston Herald added.

"I want you to focus on what you know about Wallace and Ortiz and the fact that they took PCP. Did one of them murder Odin Lloyd without Aaron Hernandez knowing about it?" the legal counsel added, noting that the two were high on drugs at that time.

According to Boston Herald, this was the first admission of the defense during the entire nine-week trial. It clearly established Hernandez's presence in the crime scene.

Prosecutors earlier argued that the former NFL player was the brains of Lloyd's killing and was working with Wallace and Ortiz to carry out the murder. He also allegedly asked his fiancee Shayanna Jenkins to get rid of the murder weapon.

For his part, lead prosecutor Will McCauley said in his closing argument that they "could ask for nothing more from a jury, but we expect nothing less than first-degree murder."

"Ask yourself ... what was the purpose of going to, I suggest to you, the most ideal place to commit a murder? During the course of the day, they're eating ... hanging out. Meanwhile the body of Odin Lloyd is in the initial stages of decomposition," McCauley said as he recounted the events prior and after the murder.

An AP report published on Yahoo Sports said that the prosecutor also claimed that the suspect's behavior after the crime showed that he was involved. McCauley said Hernandez rented a car for Wallace then instructed Jenkins to give his co-defendants $500 to escape.

The Odin Lloyd murder trial has called in 135 witnesses with only three of them coming from the defense. AP said the prosecution was able to secure so many evidence like surveillance videos, cellphone records and testimonies of witnesses establishing that Hernandez was with Lloyd when the latter was killed.

When they meet again on Wednesday, the jury will decide on Hernandez's verdict and also rule if he is guilty or innocent of unlawful possession of a firearm and unlawful possession of ammunition.
