Homicide suspect

He is wanted in connection to two homicides, a brutal assault and a home invasion in which several guns were stolen.

"Manfredonia, of Sandy Hook, is a suspect in a Friday, May 22, 2020 murder and attack on Mirtl Road in Willington, along with a killing in Derby during an ongoing three-day rampage", state police said in a press release.

Police were searching for Manfredonia in the area of Derby and Seymour on Sunday, May 24, but to no avail since he was no longer believed to be still in the area.

He did not know the victims in the Willington Assault and attacked them after they offered to give him a ride to where his motorcycle was parked. 

The victim who was killed was identified as Ted Demers (62), a woodworker. 

Demers wife, Cynthia, told the Hartford Courant her husband and the other man offered to help Manfredonia when they saw him walking on the road. He said he needed a ride back to where he had parked his motorcycle, she told the newspaper. Cynthia Demers told the Courant, “It could have been anybody who offered him a ride. It could have been any of my neighbors’ husbands. It just happened to be mine.”

She said five minutes after her husband drove away with Manfredonia on a four-wheeler, a neighbor drove up to the house and told her there had been an awful accident, according to the Courant. Police responded and found two victims and immediately began CPR. State Police spokesman Trooper Josue Dorelus told reporters the attack was “brutal.” Both victims were taken to the hospital, where Demers died, according to police.

The second victim, described as an elderly neighbor of the Demers, suffered injuries considered to be “extremely serious, potentially life threatening,” Dorelus said

Manfredonia was seen leaving the scene of the attacks in Willington on a red motorcycle, but police later found the bike abandoned. Police issued an alert on Saturday, about 5:30 p.m., identifying Manfredonia as a suspect in the slaying and assault.

Manfredonia stole guns & a car from a Willington home overnight & killed a man at a home in Derby

After the attacks on Mirtl Road in Willington, Manfredonia is believed to have broken into a home on Turnpike Road in Willington Saturday night while at least one person was home, police said. According to police, Manfredonia is believed to have stolen shotguns and a pistol from the house during the home invasion. He also stole a truck, state police said.

“The homeowner was held against his will. The suspect that we know from Willington took supplies to include food and the victim’s truck,” Trooper First Class Christine Jeltema, the state police public information officer, said at a press conference.

“We also learned that firearms were taken from the home. The victim on Turnpike Road was not injured and he refused treatment at the scene. The suspect then took the victim’s truck, drove it down to Derby where it was located near Osbornedale State Park.” 

The truck taken from the Willington home was found crashed and abandoned in Derby about 6:45 a.m. Sunday on Hawthorne Avenue at Cullens Hill Road, police said. It is not known when exactly the crash occurred. Police began searching the area of Osbornedale State Park in Seymour and Derby Sunday morning after suspecting he was possibly there. The park was closed down. But by Sunday afternoon, authorities in both towns said he was not located. The search included the area of Great Hill Road and Roosevelt Drive, also known as Route 34.

Connecticut State Police said at a press conference later Sunday a man was killed at the Roosevelt Drive home and Manfredonia is a suspect in the murder. Jeltema said Manfredonia is believed to have known the victim in that killing. The victim, identified as an acquaintance of Manfredonia, has not been publicly identified and police did not say what his relationship to to the suspect is. 

Manfredonia, in the  past raised money for anti-gun violence charities

Manfredonia was a student at Newtown High School in 2012 when 20 students and six educators were killed at Sandy Hook Elementary School in his hometown. Since then, Manfredonia has been active in raising money and awareness for anti-gun-violence groups, his social media pages show.

On Linkedin, Manfredonia, who played football at Newtown High School, said he was the marketing coordinator for Dream Ride, a Cheshire-based nonprofit. Manfredonia wrote he, “organized, developed and oversaw a marketing campaign over multiple online platforms for the Hometown Foundation, worked with the Dream Ride charity, raising money to benefit the Special Olympics and CT Law Enforcement.”

In 2019, Manfredonia posted a fundraising facebook poster saying he was participating in the 34th Annual Dave Parcells Madison Triathlon, “to raise awareness for multiple contemporary social/environmental issues".

Manfredonia said money raised during the event would support Sandy Hook Promise and a foundation set up in honor of one of the children killed in the shooting, along with Connecticut Children’s Hospital, the Environmental Defense Fund, Planned Parenthood, the World Wildlife Fund, Students for a Free Tibet, the American Foundation for Suicide Prevention and the American Brain Foundation. 

On August 4, 2019, Manfredonia wrote about mass shootings in El Paso, Texas, and Dayton, Ohio, in a Facebook post:

It is with a heavy heart that I wake up this morning and address the three mass shootings that have recently taken place; two of which were no more than 14 hours apart. I would first like to say that any public concentration should only be focused on the victims and families of these atrocities. By promoting the perpetrator and their ideology, you are only progressing their message of violence and hate and giving purpose to their action.

I would also like to say that in times like these more than ever, it is important to cherish all the people you love. Love is the only answer to hate, not more hate. By surrounding ourselves with the ones we love, we become more human. We discover the depths of our empathy, an ability that must be tuned through social interaction and emotional intelligence… a trait far too many white, male nationalists are stunted in.

Beto O’Rourke, who’s home town of El Paso was involved in the deadliest of the three, gave a speech during the event saying: “Any illusion that we have that progress is inevitable or that the change that we need is going to come of its own accord is shattered in moments like these. It is upon every single one of us [to incite change], there is no luxury in this democracy of sitting this one out.” BE THE CHANGE YOU WANT TO SEE.

Use words… not violence…

(Reminder that this is NOT a partisan political address and gun violence should not be a partisan issue as it effects all of us)

Also in August 2019, he wrote about violence in America in another Facebook post:

An irrefutable factor in this plague of violence effecting the nation MUST be attributed extremist views brought about by an environment that promotes toxic masculinity while enabling individuals with a dangerously severe lack of sympathy/remorse to freely acquire firearms. How much more will it take for people to understand SOMETHING in our system isn’t working and action needs to be taken? Remember the victims, not the shooters or their ideology. #PrayForElPaso #PrayForGilroy

Manfredonia also often posted about environmental issues. He wrote in 2019, “While I am very happy to see the plastic bag ordinance take effect in Connecticut, it only accounts for a very small fraction of the waste that ends up in our oceans! The importance of residents, business leaders, and politicians working together to find more sustainable solutions to our waste problems is absolutely paramount!”

He has a set of Instagram posts about raising awareness for causes he believes in.
