Man who killed hotel security guard struggled with mental illness, records say

KENT COUNTY, MI – The man suspected of killing a hotel security guard before turning a gun on himself struggled with mental illness and had contemplated suicide for years.

Jacob Grygorzyk, 21, is accused of shooting John Cain Jr., 38, early Tuesday, Nov.

2, at Grand Rapids Inn in Wyoming. Cain confronted Grygorzyk outside of his second-floor room to tell him that he and another man had to leave because of disorderly behavior.

Cain died on the balcony.

The slain man’s family said Grygorzyk recorded the killing on video and shared it on Snapchat, a social-media application. Wyoming police confirmed that a video related to the killing was shared on social media.

The video was taken down.

After the killing, Grygorzyk went home and shot himself, police said.

His mother’s home is a short walk from the hotel at 28th Street SW and Buchanan Avenue. She found him dead in his bedroom when she checked on him, police said.

She also found him after an earlier suicide attempt.

Grygorzyk was hospitalized April 11, 2020, after he overdosed on Xanax and alcohol in an attempt to kill himself.

After the attempted suicide, a social worker filed a petition in Kent County Probate Court seeking involuntary hospitalization because Grygorzyk posed a danger to himself and others, the petition said.

“Jacob took an overdose of pills and alcohol and left a note stating he is sorry to his family and reports he had planned to harm himself since 2016,” the social worker wrote.

“Patient acknowledges he tried to kill himself and he wants to die.”

Grygorzyk, who was being treated at Mercy Health Saint Mary’s psychiatric medical unit, agreed to a treatment plan recommended by doctors. Probate Judge David Murkowski deferred a hearing on the commitment request given Grygorzyk’s acceptance of treatment.

The plan called for up to 60 days in a psychiatric hospital and 180 days in outpatient therapy.

Grygorzyk agreed to take prescribed medications and attend counseling and therapy sessions.

Doctors said in Probate Court records that Grygorzyk suffered “acute major depression” and had felt extreme self-blame and guilt.

His mental illness caused disorder of his thoughts and moods which could “significantly alter” his judgment, behavior and ability to cope with typical demands of life, authorities said in court records.

Grygorzyk had previous run-ins with the law but no felony convictions, only misdemeanors, state police records showed.

In September 2017, he was sentenced in Wyoming District Court to 92 days in a sober-living unit after pleading guilty to attempted unlawful use of a motor vehicle.

In February 2020, he pleaded guilty in Grandville District Court to attempted resisting and obstructing police and embezzlement under £200. He was sentenced to 10 days in jail for resisting and obstructing police and fined £200 for embezzlement.

That September, he was sentenced in Wyoming District Court to 93 days in jail and 12 months on probation after he pleaded guilty to domestic violence, records showed.

A GoFundMe page to help cover funeral expenses for the victim has surpassed a £10,000 goal.

The killing devastated Cain’s family, his father, John Cain Sr. told MLive on Tuesday, the day his son was killed.

John Cain Jr. left an 8-year-old daughter, Niahmari. He adored her.

He was her best friend.

The father said Grygorzyk “took the easy way out” by killing himself.

The slain guard did not know Gygorzyk, police said.

The younger Cain was also known to many as a football coach, from young kids to those playing semi-professional.

He was in the process of starting a new team, the Grand Rapids WildKats.

He acted as a mentor to many young athletes, his father said.

“He was a good son, a great father, an uncle, a mentor, a football coach,” his father said.
