MUNDELEIN — Two people died and one was injured after an apparent murder-suicide Wednesday.

Alina S. Rybinkova, 22, was found dead about 1:30 a.m. in a garage at 1397 Newport St., on the village’s south side, and a 44-year-old man — Gennadiy Plaksa of Palatine — was found dead in a car about 300 feet away. Plaksa died of an apparent self-inflicted gunshot wound, police said.

“It’s still an ongoing investigation right now,” said Mundelein Deputy Police Chief John Monahan. “By no means is the investigation complete. There are still some other facts we need to follow up on.”

The Lake County Coroner’s Office conducted an autopsy on Rybinkova late Wednesday, and plan to autopsy Plaksa today, Jan. 12.

Monahan said Plaksa had previously had a relationship with the victim’s mother, which had ended. He said the mother had been staying with her daughter, Alina.

Police believe that sometime after 9 p.m. Tuesday, Plaksa broke into the home to gain entry. Rybnikova arrived home a short time later and was confronted by Plaksa, who struck the victim several times with a blunt object, Monahan said.

Later that evening, the victim’s 45-year-old mother arrived home from dinner and was assaulted by Plaska, who knocked her to the ground, placed her hands behind her back and handcuffed her, Monahan said.

After talking with Plaksa, the woman was able to convince him to release her from her constraints, he said. The woman then called her daughter’s roommate and asked her to come home.

When the roommate arrived at about 1:30 a.m. Wednesday, Plaksa and the woman’s mother were standing near the front door and as she started to pull into the driveway Plaksa began walking down the street away from the home. They then opened the garage and discovered Rybinkova’s body and called 9-1-1.

Until then, the mother did not know her daughter was lying dead in the garage, Monahan said.

“She’s distraught over the loss of her daughter,” he said.

There are no police reports of any domestic disturbances between Plaska and his former girlfriend in Mundelein prior to the attack, Monahan said.

In fact, Plaksa previously had visited the townhouse in December to urge his former girlfriend to reconcile with him, but she refused, and the meeting ended peacefully with Plaksa leaving, Monahan said.

“He had tried to speak with her and regain a relationship, but she had no interest in that,” Monahan said.

Neighbors were shocked when they learned of the news.

“It saddened me the whole morning. It’s an eerie feeling,” said Lorri Estell, who lives in a townhouse across the street from where the incident occurred.

Investigators on the scene Wednesday were seen dusting for prints on a window that had been broken in. A car was towed away from the scene.

The Lake County Major Crime Task Force is assisting in the investigation.
