The Dane County Medical Examiner's Office released the name of the man who died in an officer-involved shooting in the town of Primrose on Thursday.
Fifty-year-old Dean Caccamo was pronounced dead at the scene by a Med Flight physician. The Medical Examiner's Office released results from a preliminary autopsy that show Caccamo died from a single gunshot wound.
Dane County Sheriff Dave Mahoney said Caccamo suffered from mental illness.
Mahoney held a news conference Friday about the incident at 233 Hanna Road in which four people were injured, including two deputies.
Deputies were called to the home at 12:35 p.m. on reports of a severely injured elderly woman and an older man with a significant head injury, Mahoney said. The deputies entered the home to make contact with other possible family members.
Mahoney said Lt. Brian Hayes and Deputy Roger Finch found the son of the injured couple in the basement. He said Hayes had a weapon that shot non-lethal beanbags that was grabbed by the son while at the same time the deputy received a significant stab wound as well as laceration to his thigh. Hayes was able to descend the stairs, while at the same time, deputy Finch received a stab wound to his knee and upper thigh. Mahoney said they used a spray and a baton and twice used a Taser to try to take the man into custody.
A third deputy, James Kelley, fired one shot, hitting the man in the shoulder.
The man was wearing a bullet-proof vest, Mahoney said, and assaulted the deputies as they tried to come down a narrow staircase. He said deputies had been in contact with the man in the past. He said the man suffered from long standing schizophrenia and had previously been in facilities and halfway homes, but was most recently staying with his mother and stepfather.
The deputies were stabbed in the legs, Mahoney said, but their injuries were non-life-threatening. Finch was released from the hospital on Friday. Hayes has also been released from the hospital.
Mahoney said the deputies involved described the scene as a battleground and said there was clear evidence of where the assault of the couple had occurred. The couple has also been released from the hospital.
Each deputy has about 20 years of service on the force, Mahoney said.
Mahoney said the two people deputies originally found injured are the homeowners.
According to property records, Rosemary Hansen and Robert Hansen have owned the residence at 233 Hanna Road for the last 15 years.
Kelley and five other deputies involved in the incident are on administrative leave in accordance with the department's policies.
According to a release, the Dane County Sheriff's Office Officer-Involved Shooting Protocol has been initiated, and investigators from the Sun Prairie Police Department, Madison Police Department, Fitchburg Police Department and UW Police Department are leading the investigation with the assistance of the Dane County Sheriff's Office.
