WINDSOR LOCKS, Conn. (WTNH) — A 70-year-old Windsor Locks woman was sent to the hospital Thursday after being ambushed during her workout, according to police.

The woman was “exercise walk-jogging” at about 10 a.m. on Old County Road when a stranger ran up behind her and punched her in the head, according to Windsor Locks police. Nothing was stolen.

“I looked down the road, and there was a lady down there that was on the ground down there, and a police officer had a towel on her head, and it looked like she got whacked in the back of the head with something,” Shaun Terra said.

Officers and K-9 units searched the area, and the man was found by Connecticut State Police troopers on Schoephoester Road.

Troopers stationed at Bradley International Airport were able to quickly get to the area and make an arrest, according to Lt. Paul Cherniack with the Windsor Locks Police Department.

The woman remains in the hospital with a serious head injury, according to police. She also has broken fingers.

“She is hurting pretty bad, she is still in the hospital and will remain there at least for the near future,” Cherniack said. “We are monitoring her condition and praying for a speedy recovery.”

Alexander Lesuer Russell, 40, is facing charges of first-degree assault on an elderly person and first-degree reckless endangerment. He has been assigned a $150,000 bond and will appear in court on Friday.

Cherniack said Russell has “signs of violence in his history,” but nothing from that area. He is also known to the police.

Russell is not cooperating with officers, according to Cherniack, and they still don’t know why he attacked the woman. Police are investigating to see if the incident could be connected to the TikTok “knockout game,” where users are challenged to render someone unconscious with a single blow.
