Almost a week after a man was killed in a parking lot in Prince George’s County, Maryland, police said they are still without a suspect in the case.
With the hope of finding witnesses who can lead them to 22-year-old Mamadou Bah鈥檚 killer, detectives returned to the scene in Adelphi on Thursday to speak with residents.
鈥淩ight now, we鈥檙e working with very little,鈥 said Officer Ameera Abdullah, with Prince George鈥檚 County police.

It was last Friday that Bah鈥檚 uncle Mamadou Diallo said his nephew brought him home because Diallo鈥檚 car was in the shop.
After dropping him off, Diallo said Bah turned down an invitation to join him for dinner and decided to head home instead, promising Diallo he would call once he reached home.
That call never came.
At around 7:30 p.m. police said Bah was shot multiple times in the parking lot of the Presidential Towers Condominium building where he lived.
Diallo said Bah, who was named after him, and came to the United States from Guinea, West Africa, to study English. In January, Bah would have begun studying for his master鈥檚 degree at an area college.
Diallo described his nephew as a quiet person, who was helpful, attentive, respectful and “nice to everybody.”
As his family copes with the loss, Diallo said his only hope is that his nephew鈥檚 killer can be brought to justice.
“If some people can help us to find who did that, that鈥檚 gonna be good,” Diallo said.
This the second time since the killing that detectives returned to the parking lot to see if they could find anyone who heard or saw anything the night of Oct. 11. Police also handed out fliers with Bah鈥檚 picture and information about the case.
Bah鈥檚 roommate, Boubacar Diallo, said he and Bah became close friends over the past two years.
鈥淚鈥檓 shocked. There is nothing that I can say,” Boubacar Diallo said, adding that he just wants to know the truth about what happened to his friend.
Bah’s roommate hopes police will get the information needed to solve the case and arrest those responsible for his death.
鈥淎ll his family is back there. They鈥檙e crying; they don鈥檛 know what happened to their kid,鈥 Boubacar Diallo said.

There is a $25,000 reward being offered in the case. Anyone with information should call the police department鈥檚 homicide unit at 301-772-4925. People who want to remain anonymous can contact Crime Solvers at 1-866-411-TIPS (8477), or go online at .
