Superior, WI (NNCNOW.com)--- Day two of the Tiawain Johnson murder trial continued in Superior today with several witnesses taking the stand for the state.

Deputy Chief Nicholas Alexander with the Superior Police Department, one of the investigators in this case, was on the stand for nearly four hours today.

Alexander introduced a possibly key piece of evidence...surveillance video from VIP Pizza near the crime scene.

The video does not identify Johnson or Cooper, but shows a man walking up to another man with his arm extended.

Deputy Chief Alexander testified he believes the approaching man is Johnson.

The video shows the victim falling back, and the shooter running away...the victim then runs into a house on 12th and Banks.

The defense questioned Alexander about a voicemail left on the victim's phone the same day as an alleged robbery of Tiawain Johnson.

The voicemail was left by a number linked to Rayard Herron- a witness and former suspect in the case, threatening to kill Cooper.

Perhaps the most compelling testimony came from Angella Baumgartner, who was with Cooper in his final moments.

Baumgartner was lying down when she heard the noises and yelling outside of her home .. she will never forget what happened next.

"He just came running in yelling something and we were all trying to figure out, cuz it kinda sounded like either they got me or they shot me, something like that and that was when he was first coming in the door I was in my room at that time and by the time I came out he was laying on the floor," said Angella Baumgartner.

The medical examiner testified that Cooper was actually shot twice..once in the leg and the fatal shot to the chest that went through his heart.

Dr. Ann Bracey said there was no way that wound could have been repaired.

The state will continue calling witnesses Wednesday.

The trial is expected to wrap up on Friday.
