O'FALLON, Mo. (KMOV.com) -- We've been telling you about Pamela Hupp for weeks.

Hupp is charged with killing a man in St. Charles County. She was also a witness in a murder case in Lincoln County from 2011.

As News 4 reported in late August, the death of Hupp's mother, Shirley Neumann is raising new questions.

For the first time ever, we are getting a look at the scene of Neumann's death.

Investigative Reporter Lauren Trager got pictures from a source tied to the investigation.

Shirley Neumann’s death was initially investigated as suspicious, but was ruled accidental. At this time, the case has not been officially re-opened, though police are looking for additional information.

With all the recent events involving Hupp, the News 4 I-Team took a deeper look. They showed everything we've gathered to several experts in criminal law. To be clear, they are not directly involved.

But our experts say they see some serious inconsistencies and unanswered questions.

They want to know more about the broken balcony bars. One expert also said Neumann’s injuries aren't necessarily consistent with the impact from the bars.

According to police, Pamela Hupp was the last person to see Neumann alive after dropping her off at the facility following a brief hospital stay.

Hupp reportedly told staff that Neumann would not be down for dinner or breakfast.

Later the next day, a staff member went to Neumann’s apartment to check on her. She reportedly found the door cracked, water running in the bathroom, and Neumann’s body below the balcony.

Detectives ruled the incident an accidental death. But one month later, they received an anonymous email asking them to look into it again, so they did. Again, they did not find any evidence to suggest anything other than an accident.

The Medical Examiner’s Office said Neumann died of blunt force trauma to the chest and said the manner of death was accidental.

The Neumann family is suing the retirement home, the railing company and several others. Several representatives declined to comment.

It appears Neumann had a life insurance policy, but we don't know if Pam Hupp got any of that money.

Hupp remains in jail on unrelated murder charges in St. Charles County.
