Upon arrival at Sypien’s family residence on Bittersweet Road, officers located a male subject on the front lawn suffering from what appears to be a self-inflicted gunshot wound. The subject was identified as Sypien.

Sypien was transported to Delnor Hospital in Geneva with a potential life-threatening injuries. No other persons were injured during the incident.

At around 7:38 p.m. Wednesday, the Sheriff’s Office announced that Sypien was pronounced deceased shortly after his arrival at Delnor Hospital.

According to an article in the Daily Herald, which was shared on the Kane County Sheriff’s Office Facebook page, Sypien, 51, of Dublin, CA, was wanted in the murder of John Moore, 76, of Danville, CA.

An article in the San Jose Mercury News said Moore was shot multiple times and killed Sunday in a parking lot in Danville, CA.

Four years earlier, Moore had typed up a document seeking a restraining order, predicting Sypien would one day harm him or his family and describing Sypien as “a sociopath.” The Mercury News article said Sypien had dated Moore’s daughter in the late 2000s, was abusive to his girlfriend and her daughters and continued to harass the family for years.

Authorities were concerned that Sypien might flee to his parents’ home on Bittersweet Road in St. Charles Township, so Kane County Sheriff Ron Hain notified residents of the area to be on the lookout, the Daily Herald said.

A neighbor saw Sypien and called 9-1-1. Just as police and sheriff’s deputies were arriving on the scene, Sypien used a handgun to shoot himself in the head, the Sheriff’s Office said.
