A 57-year-old Florida man hid behind an apartment building and waited for a man on an ATV to drive by before he shot him to death following a complaint about him riding in the complex, authorities say.

Ralph Francis Hensel stands accused of first-degree murder in the death of 32-year-old Ja’Keem Williams. According to a probable cause arrest affidavit, the leasing office manager at the Bay Pointe apartments in Winter Garden, an Orlando suburb, called police just before 4 p.m. to complain about a man riding an ATV in the complex. Just a minute later, another call came in to report that someone had been shot.

Cops arrived on scene and found a resident completing CPR on a man later identified as Williams. But it was “apparent he was deceased,” the affidavit said. Witnesses told officers they saw Hensel, armed with a gun, walk from the leasing area toward Williams as he drove the ATV. Hensel shouted something at Williams, but witnesses could not make out what he was saying. Shortly after that, the witnesses heard two loud bangs.

Hensel allegedly walked back to the leasing office and said “I killed him.” Cops on scene took Hensel into custody and recovered a gun nearby. Surveillance video confirmed that Hensel was allegedly the shooter. It showed him walking from the leasing office and around a nearby building with his firearm, where he stood “lying in wait,” according to police. Hensel then shot Williams as he rode past, cops said.

Detectives also reviewed the 911 call from the office manager with a man in the background saying “that motherf—er’s dead,” according to the affidavit.

Local CBS affiliate WKMG said it knocked on the door of Hansel’s apartment. The woman who answered was the leasing manager that initially called 911. She told the outlet she lived with Hansel but declined to speak further because the complex’s owners told her not to speak publicly about the case.

Joseph White, 41, learned his fate on Thursday in the death of Christopher Foster, 28, Baltimore City State’s Attorney Ivan J. Bates announced in a press release. White was found guilty of second-degree murder and given the maximum penalty of 40 years in prison.

“This horrific and shocking act demands the absolute severest consequences,” said Bates. “In a callous act of violence, the defendant pushed the victim not once, but twice, ensuring that he tragically fell from the subway station platform to his death. It is unfathomable to consider the anguish of a family awaiting a loved one who will never return due to such senseless brutality. My heart goes out to Mr. Foster’s family as they navigate this profound and unbearable loss.”
