UPDATED (7:35 p.m. ET) to add WGN report that Gliniewicz allegedly arranged sham marriage for his son.

An official says an Illinois police officer who killed himself tried to arrange for a gang member "to put a hit" on a village administrator because he feared she would discover he had been embezzling money.

Lake County Sheriff's Office spokesman Christopher Covelli also said Thursday that investigators found packets of cocaine in Fox Lake Police Lt. Charles Joseph Gliniewicz's desk after his Sept. 1 death.

Covelli says investigators recovered deleted text messages in which Gliniewicz mentioned the possibility of planting something on the administrator, Anne Marrin, although he said they don't know if that's why he had the cocaine.

Text messages from Gliniewicz authorities have recovered.

(For reference, Volo Bog, seen above, is a nearby nature reserve.)

Covelli says Gliniewicz sent the text about arranging the hit to a woman last April, asking for help arranging a meeting with a high-ranking gang member. He declined to give her name.

Officials released a collection of incriminating text and Facebook messages Gliniewicz had sent and received which can be read below.

Surviving family members also under investigation

Meanwhile, Gliniewicz's wife and son are also under criminal investigation. The official, who was briefed on the investigation, told The Associated Press's Don Babwin Thursday that it centers on the Fox Lake Police Explorer Post from which Gliniewicz allegedly stole thousands of dollars over the course of seven years.

The official spoke on condition of anonymity because he was not authorized to discuss the investigation publicly.

He said Gliniewicz's wife, Melodie, and son D.J. are caught up in the probe. Melodie Gliniewicz took part in the Explorer program. D.J. Gliniewicz has angrily dismissed suggestions that his father took his own life.

And WGN reported Thursday night that Gliniewicz apparently set up a sham marriage between a woman with whom he had carried on an affair and his son so that his son's military benefits would receive a significant boost.

As the investigation continues, the 100 Club of Chicago has requested a return of a donation it gave to Gliniewicz's family.

Past troubles for officer

While Gliniewicz received a hero's burial upon his death, the perception of the officer - and his past - has quickly shifted in the wake of the recent revelations.

George Filenko, head of the task force investigating Gliniewicz's death, said on Wednesday, "This is the first time as a law enforcement officer … that I've felt ashamed by the acts of another police officer. Gliniewicz committed the ultimate betrayal to the citizens he served and the entire law enforcement community."

With the current investigation ongoing, local media has dug up old allegations against Gliniewicz, including a 2001 case in which he was suspended for 30 days for sexual harassment.

The task force also discovered that Gliniewicz, who radioed in about spotting three suspicious men before his death, had actually spotted a trio of men, intending to peg his death on them in an attempt to cover up his suicide.

One of the men who was considered a suspect, Thomas Corso, told ABC 7 Chicago, "I'd be in jail right now. He tried to pin it on us."

"Black Lives Matter" correlations

Since Gliniewicz's death, some politicians and pundits linked his death either directly or indirectly to the Black Lives Matter movement which has been outspoken on its criticism towards police abuse of African-Americans, particularly in the wake of the deaths of Michael Brown in Ferguson, Missouri, Tamir Rice in Cleveland, Ohio, and Eric Garner in New York.

The Washington Post has rounded up a list of those who have done so but perhaps one of the more high-profile examples is New Jersey governor and GOP presidential candidate Chris Christie and Fox News. During an appearance on "Fox & Friends" a few days after Gliniewicz's death, one of the hosts's linked his death to threats from the movement and Christie responded with bombastic criticism himself.

Christie would later double-down on his Obama/Black Lives Matter criticism on a late-October appearance on "Face The Nation."

Other GOP presidential candidates including Wisconsin Gov. Scott Walker (who has since dropped out) and Texas senator Ted Cruz made similar correlations.

And an op-ed in USA Today by Ron Hosko, president of the Law Enforcement Legal Defense Fund, did the same, lumping Gliniewicz's death in with the death of Texas Sheriff Deputy Darren Goforth.
