"It is with heavy hearts that the Suffolk County Sheriff's Office announces the passing of Investigator Sergeant Keith Allison," the department said. "Inv. Sgt. Allison was hospitalized with serious COVID-19 complications last week and succumbed to the illness on Thursday, December 17, 2020."
Allison started his career with the Suffolk County Sheriff's Office in 1995 and celebrated his 25th year of service this past February.
"I am deeply saddened by the loss of Inv. Sgt. Keith Allison," Sheriff Errol Toulon said. "He was an excellent officer, a husband, father, and grandfather who was deeply committed to his family and the Sheriff's Office. We all have heavy hearts on his passing."

After a short period of time as a correction officer at the Riverhead Correctional Facility, Allison began working for the Personnel Investigations Bureau, conducting background investigations and interviews for new employees, both uniformed and civilian.
He later became the commanding officer of the Personnel Investigations Bureau and was promoted to Investigator Sergeant in 2018.
Because of his long tenure with the Personnel Investigations Bureau, he helped many of the current Sheriff's Office employees through the hiring process.
"He will be missed by all," the department said.
