The number of murder and nonnegligent manslaughter offenses across the country increased 29.4% in 2020, according to FBI data released Monday.

The numbers show the estimated number of violent crimes increased from the previous year, something that has not happened in four years, the FBI said. Overall last year, violent crime including murder, manslaughter, rape, assault and robbery was up 5.6 percent from 2019.

The 2020 data shows the estimated rate of violent crime was 387.8 offenses per 100,000 people, the FBI said. The estimated rate of property crime was 1,958.2 offenses per 100,000 people, marking an 8.1% decline in property crimes, the agency said.

Georgia saw a marked increase in its violent crime rate, outpacing the U.S. average. Of the 657 law enforcement agencies in the state, 399 elected to submit an expanded homicide report for 2020, the FBI said. For the 2019 report, 276 of 658 agencies participated.

In Atlanta, 2020 was the deadliest year in decades. The Atlanta Police Department investigated 157 homicide cases last year, up from 99 in 2019 and the most in more than two decades.

No corner of the city was spared. Kevin Humes, 35, was shot to death in May 2020 outside a Buckhead apartment complex. The following month Jalanni Pless, 18, was shot to death while selling water in Midtown and Andrew Scott Callahan, 37, was shot near the Historic Fourth Ward Skatepark. Kalecia “Pinky” Williams, 16, was shot in December at a downtown hotel.

“As a parent, it never crossed my mind to lose my child to gun violence, let alone a homicide,” Tomeka Pless, Jalanni’s mother, said Monday.

Jalanni was shot over $10, according to investigators. Recently, the woman who gave him the cash contacted Tomeka Pless. Jalanni had been respectful and was humbled before he was shot and killed by another teenager, allegedly claiming he was owed the cash.

“They don’t fight and let it go anymore,” Tomeka Pless said. “They fight and they come back and retaliate. It’s just too much.”

As of June, the Atlanta Police Department reported a nearly a 60% increase in homicide cases over 2020; the pace has since slowed. As of Monday, APD had worked 121 homicide cases in 2021. By this time last year, Atlanta police had investigated 99 homicides, according to department data.

Mayor Keisha Lance Bottoms has often referred to the spikes as a “COVID crime wave,” pushing back against critics who say she hasn’t done enough to combat the issues.

The national violent crime rate last year was 399 offenses per 100,000 people in the country, according to the data. In Georgia, the violent crime rate climbed from 325 per capita offenses, far below the national average, to 400, just above the U.S. number. While authorities in Atlanta and even rural areas have grappled with increases, the state data is difficult to parse quickly because of the increase in the number of departments reporting.

In 2019, 276 Georgia agencies reported crime data to the feds while 398 agencies offered numbers last year. The GBI, which corrals data from agencies around the state, didn’t immediately give a reason for the increase.

The U.S. data says property crimes dropped almost 8 percent, making 2020 the 18th consecutive year of decreases in such offenses.

Law enforcement agencies across metro Atlanta reported a sharp decrease in crime rates in early 2020, when coronavirus concerns spurred lockdowns and shuttered many businesses, malls, restaurants, schools and government buildings. The lull didn’t last.

Local data shows upticks in violent crime in communities across Georgia. Last week, an investigation by The Atlanta Journal-Constitution showed that towns and cities across the state also are grappling with homicide spikes. Spalding County, for instance, saw nine killings in 2020, up from one the prior year.

“It’s a problem — big towns, little towns,” LaGrange Mayor Jim Thornton, who serves as president of the Georgia Municipal Association, told the newspaper. “Obviously, Atlanta gets the headlines but it really is ubiquitous — it’s everywhere.”
