An 84-year-old white man charged in the shooting and wounding of a black teenager who mistakenly walked up to the man’s house in Kansas City surrendered to police, the Clay County Sheriff’s Office said on Tuesday, but was freed on bond within a few hours.

Andrew Lester had been charged a day earlier with first-degree assault, which could bring a sentence of life in prison, for shooting Ralph Yarl, 16, on the doorstep of his suburban home around 10 p.m. last Thursday.

Yarl had walked up to Lester’s house to pick up his younger siblings, who were at a nearby house with a similar address.

Lester was also charged with armed criminal action, punishable by up to 15 years in prison.

“Andrew Lester, charged in the shooting of Ralph Yarl, has surrendered at our Detention Center. He is in custody,” the Clay County Sheriff said earlier on Twitter.

Bond for Lester was set at $200,000, which he posted within a few hours of turning himself in to authorities, the Clay County Sheriff’s office said on social media late Tuesday afternoon.

“I can tell you there was a racial component to the case,” Clay County prosecutor Zachary Thompson told a news conference, without providing further details.

Prosecutors have not filed hate crime charges, which carry lesser penalties in Missouri than the two counts Lester faces, Thompson added.

Lester fired two shots through a glass door with a .32-caliber revolver, the prosecutor said. Yarl, who was struck in the head and an arm, did not cross the threshold, Thompson said, adding it did not appear any words were exchanged in the encounter.

But Yarl told police in an interview at the hospital where he was treated that the man told him, “Don’t come around here,” local media reported, citing court documents.

The teen was recovering at home on Monday, his family said.

Lester was initially taken into custody, placed on a 24-hour investigative hold, then released pending an interview with Yarl and the collection of forensic evidence, Kansas City Police Chief Stacey Graves said.

His swift release helped fuel two days of protests.

Missouri has a “stand your ground” law that allows homeowners to use physical force to defend themselves against suspected intruders.

The law says a person cannot use deadly force unless they reasonably believe it is necessary to protect themselves or another person against death or serious physical injury, or a possible felony.
