Frank Areco, the son of Larry San Nicolas, who was fatally shot by a Grandview police officer on Sunday, says his father arms were up when he was shot and killed.
San Nicholas, 60-year-old diabetic was having a manic reaction because he needed insulin.
Jessie San Nicolas, Larry's wife, wanted police to come along with paramedics to help her husband, which is what they did over a year ago when she dialed 911 for assistance with the same issue.
But this time it didn't end the same way.
"His arms were up the whole time," Arceo said after viewing video of the tragic incident taken by a neighbor across the street.
"He was not threatening the officers. There was distance between him and the officers. And they were behind cover," he told KansasCity.com
Officers responded to the residence at around 2:40 p.m. on Sunday when Nicolas walked out of the side door then down the driveway with the sword over his head.
Two officers can be seen positioned behind an SUV parked across the drive way.
One officer behind a police vehicle fires beanbag shots at San Nicolas, but he witnesses said he continued to advance down the driveway.
Then, the officer the Jeep fires several rounds at Nicolas, killing him.
Arceo, who lives across the street from his father, attempted to run to his house to keep him inside, but officers held the family back and stopped him from intervening.
He said he wants the video to be released so people can see what happened.
Grandview police turned the video over to Missouri Highway Patrol.
Sergeant bill Lowe of the Missouri Highway patrol said someone sent him a link to the video on Thursday and that he was aware of it.
But Lowe says the video doesn't provide a clear picture of the shooting and said a dash cam video shows a more complete picture of what happened.
However, the highway patrol is not releasing that video to the public until their investigation is complete, which they say they expect to take two to three weeks to review witness statements and autopsy reports.
The result of their investigation will then be handed over to the Jackson County prosecutor's office to determine whether or not charges should be filed.
