A 21-year-old woman who had just graduated from college was struck by a car and killed early Sunday in a hit-and-run incident in College Park, authorities said.

The woman, identified as Janelle Marie Oni of Randallstown, Md., was killed about 3 a.m. on the same stretch of roadway where two other pedestrians had been killed in separate incidents earlier this year.

Oni was struck around 3 a..m. in the 7600 block of Baltimore Avenue, the Prince George’s County police said.

They said that a man was arrested shortly after the incident. He was identified as Jacky Luangraj, 33, of Manassas.

Police said that Luangraj was facing 13 charges, including negligent auto homicide-under the influence, driving under the influence and reckless endangerment.

At the time of his arrest, his blood alcohol reading was twice the legal limit, police said in a statement.

Reached Sunday night at the family home in Randallstown, Oni’s mother, Ana Burnett, called her daughter “a bright shining star” who “had a bright future ahead of her.”

Burnett said her daughter had just graduated from Salisbury University in Salisbury, Md., with a degree in communications and conflict resolution.

Oni was planning to begin work on a master’s degree, her mother said. She said her daughter hoped to teach at the college or high school level, with the aim of helping young people.

The area where the incident occurred is a bustling commercial zone just south of the main campus of the University of Maryland, and houses many stores and restaurants.

The 21-year-old had been having dinner with sorority friends, her mother said.

She was preparing to go home and had called her mother a little earlier to say she was coming, Burnett said.

Apparently, she had left the restaurant shortly before her friends, who did not see what happened to her, her mother said, adding that she herself was trying to learn exactly what happened.

“She was a special person,” Burnett said. “She touched lives . . . I could not have asked for a better daughter.”

The person who struck her daughter “took my star,” Burnett said. “He took my angel.”

Police said their investigation indicated that Oni was struck by a driver who was headed north on Baltimore Avenue and did not stay at the scene. They said a minivan was stopped shortly afterward at Baltimore Avenue and the Capital Beltway.
