A jury trial began Monday for a Crystal Lake man accused of selling heroin to another man who died of an overdose the next day.
Keith L. Lang, 32, is charged with drug-induced homicide in connection with the death of 23-year-old McHenry man Scott Koivisto. If convicted, Lang could be sentenced to between six and 30 years in prison.
Lang, who remained in custody Monday at the McHenry County Jail on a $500,000 bond, appeared in court wearing a blue button-down shirt and pants as he sat beside his attorneys, Evan Randall and William Bligh.
Koivisto, 23, died on Sept. 22, 2017, from a fatal dose of a mixture of heroin and fentanyl, authorities have said. McHenry County sheriff’s deputies found his body in a residence in the 3100 block of Bull Valley Road near McHenry.
First to testify Monday was Lang's co-defendant, 26-year-old Elizabeth Long. Long pleaded guilty in 2018 to possession with intent to deliver heroin in connection with Koivisto’s death and was sentenced to six years in prison. She was released on parole in March, Illinois Department of Corrections records show.
Long testified Monday that Lang sold her drugs, which she bought for Koivisto, on Sept. 21, 2017.
When sheriff's deputies were called to Koivisto's house the following day, police found the man in his bedroom surrounded by suspected drug paraphernalia, McHenry County Sheriff's Office Detective Caitlynn Kelly testified Monday.
Following an eight-month investigation into Koivisto’s death, deputies with the McHenry County Sheriff’s Office Narcotics Task Force used a warrant on June 20, 2018, to search Lang’s home.
There, they found three semi-automatic firearms and hundreds of rounds of ammunition, authorities said. Lang, who has a past felony conviction of possession of a controlled substance and violating the conditions of an electronic home monitoring order, is not allowed to possess firearms.
Police also found heroin and fentanyl residue, packaging materials, a digital scale, drug paraphernalia and multiple hypodermic syringes, authorities said at the time.
Although it was Koivisto's death that led police to search Lang's home, the discovery of drugs and several firearms inside the residence led to charges that were filed as separate case on June 21, 2018. About a year later, Lang accepted an offer from the McHenry County State's Attorney's Office and pleaded guilty to possession of a firearm as a felon. In exchange for an eight-year prison sentence, prosecutors agreed to dismiss additional counts of the same charge, court records show.
He was sentenced to an additional six years in prison in August 2019, for an unrelated charge of possession with intent to deliver a controlled substance out of Kane County, court records show.
Lang's trial will resume at 9 a.m. Tuesday at McHenry County courthouse in Woodstock with testimony from the state's final witnesses.
