A TV reporter was shot dead after a gunman returned to the scene of an earlier homicide

• A gunman who fatally shot a woman in Florida returned to the scene of the crime hours later.
• He then went on a shooting spree, killing a local news reporter and a 9-year-old girl.

A gunman who fatally shot a woman in Orange County, Florida, on Wednesday morning returned to the scene of the crime hours later and went on a shooting spree, killing a journalist and a 9-year-old girl, authorities said.

Police said they responded to the homicide of a woman in her 20s at around 11 a.m. on Wednesday in Pine Hills, about five miles east of Orlando. Police identified the woman as Nathacha Augustin, 38, Thursday morning.

Later in the day, around 4:05 p.m., deputies received calls reporting two more shootings.

One involved two Spectrum News 13 journalists, a reporter and a photojournalist, who were reporting on the earlier homicide.

The two men were shot near their news vehicle, which was on "almost exactly the same spot" as the vehicle from the morning's homicide, police said.

Both were taken to a nearby hospital, where the reporter died. The photojournalist remains in critical condition.

The reporter was identified by police as 24-year-old Dylan Lyons and the photojournalist was identified as Jesse Walden.

Around the same time, investigators were also called to the shooting of a 9-year-old girl and her mother. Authorities said the suspect walked to their house and shot the two victims.

The 9-year-old, identified by police as T'yonna Major, died, while the mother remains in critical condition.

Deputies have detained the man they believe is behind the shootings.

Keith Melvin Moses, 19, is in custody and has been charged with one count of murder in connection with the killing of the woman in her 20s, Sheriff John Mina of Orange County Sheriff's Office said.

He noted that the woman who died was an acquaintance of the suspect. Mina said additional charges for the other shootings are expected.

The suspect's motive is currently unclear, the sheriff said, noting that it was not known if he knew the Spectrum News 13 crew members were journalists or if they were targeted.

In a statement, Spectrum News said: "We are deeply saddened by the loss of our colleague and the other lives senselessly taken today."

In the aftermath of the shooting, a video went viral of a tearful news anchor for NBC affiliate WESH 2 News commenting on the shootings.

"This is every reporter's absolutely worst nightmare," reporter Luana Munoz said. "We go home at night afraid that something like this will occur. And that is what happened here."
