Police announced Wednesday that 51-year-old Robert Simmons has been charged with the murder of 93-year-old Isabella Mehner

A man has been arrested for the murder of a 93-year-old woman who was found dead at the bottom of a staircase in her Connecticut home two months ago.

Family members of Isabella Mehner first believed her September 25 death was an accident, but on Wednesday police accused 51-year-old Robert Simmons of her murder.

Mehner lived alone at 565 Cove Road, in Stamford, prompting concern among her children when they were unable to reach her by phone.

When they arrived at the home they found her body sprawled at the foot of her basement stairs, with blood pooled around her head.

Police responded to a 911 call that an elderly woman had suffered a fatal fall down the stairs, but a subsequent investigation would later determine Mehner’s injuries were not consistent with an accident, rather a homicide.

Investigators also found that a number of Mehner’s personal item were missing from the home, with the help of her family.

Simmons was found on surveillance video loitering in the area near Cove Road and Willowbrook Avenue on the same day Mehner was killed, and, using DNA analysis, a spot of blood found on his pants matched that of the 93-year-old victim.

Through ‘old fashioned police work combined with some 21st-century investigative techniques’, authorities were able to unearth numerous pieces of unspecified evidence, that reportedly linked Simmons to the crime scene.

They do not believe the murder was a random act of violence and suspect Simmons was familiar with the victim, and her home, having previously been hired by the Mehner to carry out a series of ‘odd jobs’ at the property.

Roy Mehner, the victim’s son, called his mother’s death ‘very upsetting,’ to ABC7.

‘She's 93 years old,’ he said. ‘Why would you do something like that? It's just terrible.’

The cause of Mehner’s death was confirmed to be a blunt force trauma to the head by the Bureau of Criminal Investigations in September.

As well as the severity of her injuries, Mehner’s missing personal items acted as a catalyst in determining the great-grandmother had fallen victim to foul play.

‘Mrs. Mehner was a very organized person and her home was pristine,’ Lt. Michael Noto said in a press conference. ‘There were a few things that the family noticed that were missing, but the house was not ransacked.’

Mehner’s daughter Sandra Manzke says she has struggled to come to terms with her mother’s death.

‘My mother was an incredible person. She was so active,’ Manzke told the Stamford Advocate in September. ‘She remained active every day of her life. She used to say if you don’t move, that’s not good.’

Simmons has been charged with murder, felony murder and home invasion. He is being held on a $2,000,000 bond.
