As they continue to investigate last week's death of Jasen R. Smith, 44, Jefferson City, Maryland Heights police said Wednesday they're trying to talk with a man who might have seen Smith fall to the ground.
Smith and his wife, Darcy, had attended the Dave Matthews Band concert at the Hollywood Casino Amphitheater in northwestern St. Louis County on May 15.
About 11:10 p.m. - after the concert was over - the amphitheater's medical personnel were notified there was an unconscious man on the concrete pathway between the lawn and house seating areas.
The man, later identified as Smith, had "a serious head injury" and was taken to DePaul Hospital in Bridgeton, where he died Thursday.
His memorial service was this past Monday.
In a Wednesday afternoon news release, Maryland Heights police said their "ongoing investigation has determined that a person, described as a white male in his late 20s, may have witnessed the victim fall to the pavement. This person summoned a security guard and stated that he saw the injured man and that his injuries were very serious."
That person also told the security guard "that he was in the medical field, and that is why he felt the injuries were very serious," the Maryland Heights police reported.
The Maryland Heights police said they "would like to speak with this person - or speak with anyone who may have specific information about this incident."
It still is being investigated as a "suspicious death," and Maryland Heights police continue to ask "for the public's help in providing any information."
Anyone with information about Jasen Smith's death is asked to contact the Maryland Heights Police Department by telephone at 314-298-8700.
Jasen and Darcy Smith were married in 2014. He is survived by his wife and two sons, as well as his parents, Ronnie and Vicki Smith, and a sister, Jennifer Oster.
