Megan Boken, 23, was shot and killed in her car while she was visiting St. Louis Saturday.

Police in St. Louis are investigating the fatal shooting of a 23-year-old Chicago woman, who was killed Saturday.  

Officials say 23-year-old Megan Boken was found at about 2:20 p.m. in her parked car Saturday near an intersection in the Central West End of St. Louis with gunshot wounds to her chest and neck.

Witnesses told police Boken was sitting in her Volkswagen outside of her former residence in St. Louis.  

Witnesses told police they saw a man either get out of Boken’s Volkswagen or open the door to the vehicle. The two appeared to be arguing, and then the man fired shots into the car. She was shot in the neck and chest and later pronounced dead at Barnes Jewish Hospital.

Police said they have no evidence that Boken knew her killer, who fled the scene on foot before police arrived. Police are reviewing street surveillance video hoping to find a lead on the gunman, David Marzullo, Director of Public Information at the St. Louis Police Department told NBC News.

Police have not released a motive in the shooting but are investigating the case as a homicide. The suspect was described as a black man believed to be in his mid-20s, about 5 feet, 8 inches tall, with a thin build and short hair. No arrests have been made.

Boken was a four-year volleyball player and 2011 graduate of St. Louis University with a bachelor’s degree in business administration with a concentration in marketing, the university said in a press release. She was living in the Chicago area but was in St. Louis to play in an alumni volleyball game on Saturday. The incident occurred less than two hours before the game.

“Megan was a wonderful and beautiful human being loved by everyone she met,” Boken’s aunt Mary Pataki said in a statement on behalf of her family. “The family and the community are devastated by this senseless tragedy. And the family would like to thank everyone for their outpouring of support.”

Also mourning the loss of Boken was SLU's athletic director Chris May, who told the Chicago Tribune that although players noticed she wasn't at the game, nobody knew what had happened to the standout student until the game was over.

“Megan was one of those vibrant student athletes who participated,” May said. “She was a volleyball student athlete in business school. [She] was one of those great young women who believed in everything that St. Louis University was about. She served the community and she’ll be sorely missed for sure.”
