Two men are dead and another is in critical condition after a series of shootings late Saturday and early Sunday in Casco and Naples, authorities said.

Norman J. Strobel, 59, of Naples was shot dead in a confrontation with Cumberland County sheriff’s deputies early Sunday at a mobile home on Songo School Road in Naples, according to Stephen McCausland, spokesman for the Maine Department of Public Safety. An unidentified 55-year-old man was found shot to death inside the mobile home, where he lived.

Strobel, who had a lengthy criminal record, was sought in connection with a shooting Saturday night at a camp in Casco that left one man critically wounded. The man found dead in Naples also may have been involved in the earlier shooting, McCausland said Sunday night.

According to the Cumberland County Sheriff’s Office, Strobel and another man approached a camp on Winifred Lane in Casco that belongs to Strobel’s ex-girlfriend – identified later as Sandra Goulet – around 10:45 p.m. Saturday.

Sheriff Kevin Joyce said Strobel pounded on the door of the residence and identified himself as a Cumberland County sheriff’s deputy, WCSH-TV reported.

Goulet was not in the home, but when her daughter Alyssa Goulet, 28, of Middletown, Rhode Island, and Jason Almeida, 32, also of Middletown, came to the window, Strobel opened fire on them with a handgun, hitting Almeida four times, authorities said.

Almeida was transported to Central Maine Medical Center in Lewiston, where he underwent surgery. A nursing supervisor said Sunday night that she had no information to release about Almeida’s condition.

Alyssa Goulet, who was not injured in the shooting, identified Strobel for police. Strobel also called Sandra Goulet to admit he was involved in the shooting and sheriff’s deputies used his phone to track Strobel to the Naples mobile home around 4 a.m. Sunday, the Portland TV station reported.

Deputies entered the home after seeing a man who appeared injured through a window.

Inside the home, the deputies encountered Strobel and exchanged gunfire with him, killing him, McCausland said. They also discovered the body of the 55-year-old man who lived there. Authorities had not identified him as of Sunday night pending notification of his next of kin.

Investigators suspect that the man found dead in Naples was involved in the Casco shooting, McCausland said. The vehicle used to flee the scene was a red pickup truck, the same type of vehicle owned by the dead man, according to McCausland. Police are not looking for any other people in connection with the shooting, he said.

“One man apparently drove the vehicle, the other man did the shooting,” McCausland said in a telephone interview Sunday night. “What we don’t know at this point is if he was forced to go there or went willingly. We may never have that answer.”

Sandra Goulet had a protection from abuse order against Strobel, which he repeatedly violated, most recently in September, according to the Maine State Bureau of Identification. In that case, Strobel received two years’ probation and a 364-day suspended sentence for violating the order.

In the past week, Goulet reported that Strobel had come to her home and taken her two dogs, McCausland said. The dogs were found safe Sunday at the mobile home in Naples.

Strobel had a lengthy criminal history in his native Rhode Island, where he racked up multiple felonies between 1985 and 2001, including assault, sexual assault and attempted breaking and entering, according to the Rhode Island Judiciary’s website.

His run-ins with police continued after he moved to Maine. Starting in 2010, Strobel was found guilty of misdemeanor assault, violating the conditions of his release, criminal trespass and repeated violations of Goulet’s protection from abuse order, according to the Maine State Bureau of Identification.

Both deputies involved in the fatal shooting of Strobel have been placed on administrative leave while the Maine Attorney General’s Office investigates, as is standard procedure in officer-involved shootings.
