A Cook County judge set bail at $1 million for the second of two defendants charged with the attempted murder of an on-duty Chicago police detective earlier this year in the South Shore neighborhood.

Samuel Flowers, 18, appeared in court Thursday on multiple felony charges including attempted first-degree murder, armed robbery and aggravated battery to a peace officer. He and 23-year-old Kenyon Washington are accused of attacking the detective in an attempted mugging.

“This is one of the most dangerous things a court can hear,” Judge Arthur Willis said during Thursday’s hearing. “It’s ridiculous.”

According to prosecutors, the detective and his partner were canvassing the 7700 block of South Yates Boulevard for surveillance cameras on Feb. 8 following a homicide in that area a day prior.

The victim — who was wearing civilian clothing — was walking toward a nearby building to meet back up with his fellow detective when he was allegedly approached by Washington and Flowers who struck him in the back of the head, knocking him to the ground.

As he tried to get up, Flowers allegedly pointed a firearm at the victim’s head and demanded his belongings. Flowers later told investigators this was a BB gun, not a real firearm, according to prosecutors.

Both Washington and Flowers allegedly kicked the detective in the head and body multiple times, and prosecutors said Washington made a “stabbing motion” toward the victim with a knife, which caused two small lacerations to his neck and shoulder.

The victim repeatedly told the men he was a police officer and that they “did not have to do this,” according to prosecutors, but they allegedly continued kicking him on the ground.

As this was going on, the second detective began hearing screams outside and approached the men, drawing his weapon on them and ordering them to get on the ground, but the suspects fled on foot.

Investigators located a knife in the area with blood on it that was later tested and matched to the victim, according to prosecutors. Earlier this month, the detective picked Washington out of a photo lineup, leading to his arrest.

During an interrogation, Washington allegedly implicated both himself and Flowers, who was arrested Tuesday evening. Washington was previously charged in this case and held without bail last weekend.

The defense attorney representing Flowers on Thursday noted that he’s still in high school and has no adult arrests on his record.

Prosecutors did not seek to hold Flowers without bail, but Willis said he felt this case would warrant it, noting that Flowers had just turned 18 at the time of the alleged offense and “jumped right into the deep end.”

“This officer is struck, allegedly by you and your co-defendant, stabbed allegedly by your co-defendant, when everyone should have known he was an officer,” the judge said. “And instead of stopping, it escalates (to) one of the most dangerous things that this court can see.”

Flowers is due back in court May 5.
