Three people have been arrested in connection to the murder of an Alabama mom who was found dead on the side of the road.

The body of 23-year-old Jennifer Raven Nevin was discovered Monday afternoon near a methane gas well on a rural road in Tuscaloosa, news station WGMA reported. She had last been seen Friday dropping off her 5-year-old son with her mother.

Koran Rashad Lewis, 23, Kendrick Ky’Andre Marshall, 16, and Vida Milagros Confetti, 20, were arrested Tuesday and charged with murder, according to officials.

“We developed some leads last night, worked on them all day today,” Tuscaloosa County Metro Homicide Unit Capt. Gary Hood told Tuscaloosa News. “We interviewed multiple people, several witnesses. We were able to develop a timeline and recreate the last days of Miss Nevin’s life.”

Lewis and Marshall were taken into custody Tuesday at Tuscaloosa County Jail, where each of them is being held on $150,000 bond. Confetti’s bond was set at $100,000.

It is not known if the suspects knew Nevin. Police have not released information about how she died.

“We’re still pursuing leads and looking for other subjects to interview,” Hood said. “There are possibly others who could be charged as well.”

Relatives have said that the 23-year-old mom suffered from substance abuse issues, but that her death was not an overdose.

“I want people to know that what happened to her wasn’t her fault. She had so much to give to society and to people,” her brother Will Nevin told AL.com. “It’s just a shame she’s not going to have that chance. It’s a shame that her son is not going to see her again.”
