An out-on-bail Connecticut man who police say killed his ex-wife was found dead this week in a storage container on his son’s property after a lengthy standoff with cops — who swarmed the home when the accused killer’s GPS monitoring bracelet turned off.

Officers descended on the Fairfield home around 5:16 p.m. Tuesday and heard James Taylor’s cellphone ringing inside the 10-by-40-foot storage container, Capt. Robert Kalamaras said.

A large team of officers — including some from the Connecticut State Police, neighboring departments and a bomb squad — took a methodical approach before finally getting in the locked-from-the-inside container. Taylor, 75, was found dead at about 10 p.m., cops said.

His cause of death was not immediately released, but investigators believe he took his own life, Kalamaras said.

“All the evidence appears that it was a suicide,” Kalamaras told The Post, declining to elaborate.

Taylor — who was free on $2 million bond after pleading not guilty to killing Catherine Taylor in February — was charged with murder, attempted murder and other counts after police said he fatally shot his 70-year-old ex and tried to kill his 45-year-old stepson on Feb. 3.

An ankle bracelet was worn as a condition for his release on bail.

Catherine Taylor had been using an app on her iPad to track Taylor’s whereabouts just before he stormed into his stepson’s home and fatally shot her with a .22-caliber rifle, police said in February.

Taylor tried to reload the weapon and shoot stepson Donald Garamella, 45, before his stepson tackled him and pinned Taylor to the floor until cops arrived, the Connecticut Post reported.

The couple had actually divorced 25 years ago, but still lived together at a home in Fairfield until May 2018 — when Taylor told his former partner to move out, according to a police report obtained by the newspaper.
