Illinois man kills father after argument over pot: prosecutors

A blood-soaked man told police he stabbed his father to death inside their Illinois home Monday after the two got in a verbal fight over marijuana, according to prosecutors.

“I am a murderer,” 20-year-old Isaac Thurston allegedly told cops after plunging a knife into his father’s chest. “I don’t know why I did it.”

Thurston was taken into custody and charged with the first-degree murder of his father, 50-year-old Perron Thurston.

Officials said the fatal argument erupted after Perron caught his son smoking cannabis inside their Chicagoland home shortly before 6:30 a.m.

Perron scolded Thurston for smoking drugs before his shift at a local coffee shop, according to a bond proffer filed with the Cook County State’s Attorney’s Office.

After telling Thurston he shouldn’t work while under the influence, Perron took his son’s phone and called the shop to tell them his con could not come in for his shift, officials said.

As they continued arguing, Thurston allegedly grabbed a knife from the butcher’s block on the family’s kitchen table and lodged it into the left side of his dad’s torso.

“Isaac just stabbed me,” Perron screamed to his wife, who ran out of bed and called 911.

The couple’s other son also raced into the kitchen and began chest compressions on his father.

Responding officials arrived to find Thurston standing with “blood on his clothes and hands.”

He allegedly admitted to the brutal crime inside the home, and further explained the argument leading up to the stabbing during an interview with investigators.

Perron was rushed to an area hospital, where he was pronounced deceased, Glenview police said.

According to loved ones, he was an active BMX biker who participated in multiple clubs and with the BMX Museum, as well as an avid ice hockey player.

The 50-year-old was also a dedicated community volunteer, who donated his time to various non-profits, including The Base Chicago, Equiticity, Friends of the Big Marsh, and Inner-City Education Program.

“He was a teacher and mentor to many, a friend to all,” his obituary reads.

Prosecutors said Perron had no history of abuse leading up to the fatal altercation and that it was the first time there was any negative physical contact between the father-and-son pair.

The arrest is Thurston’s first.

He was released from custody Tuesday on $1 million bail and placed on home electronic monitoring after a man who said he was Thurston’s uncle posted bond, according to court records.
