CLINTON, MD (WUSA9) - As police continued to hunt for the person who gunned down a convenience store clerk nearly three weeks ago, Tiawo Oduwole's family is preparing for his funeral.
Oduwole was 31 years old.
He was a husband, a father, and one of eight siblings.
About five months ago, his sister says he left his wife and two children in London to pursue a graduate degree.
"He came [to Maryland] to study," his sister said. "To make his life better - but he's gone."
Through tears, Oduwole's sister, Tammy, spoke to WUSA9 about her only brother - and pleaded with the public to come forward with information.
"He's gone. He's not going to come back. I just need that person to be caught... Someone definitely has something. And that's all we need."
On Saturday, August 20th, police say a masked person shot and killed Oduwole during a robbery attempt at the 7-Elven where he worked, in Clinton.
The suspect didn't get any money, but before fleeing the scene, they shot the 31 year old twice. Roughly 10 minutes later police say the suspect and an accomplice robbed a nearby hotel.
Oduwole died at the hospital.
His sister heard the news through some family members that live in the US.
She and Oduwole's wife were 3,600 miles away in London.
"It was [his wife's] birthday," Tammy said. "She called me to say 'did you hear from my husband? He hasn't called me. It's my birthday. I turned 30 today' - and that was on Sunday. I was like. He's going to call you - maybe the phone line is bad."
Oduwole died the day before - and his sister would eventually be the one to give his wife the news.
"I called her phone. At that time Taiwo was just running through my eyes. I thought oh my god how am I going to tell her that [her] husband is dead."
The pain isn't going away, but Oduwole's family hopes they can have justice - and that someone in the community will come forward with information.
"Please, please." she said. "This is my baby brother."
Prince George's County Police say, "the reward for information leading to an arrest and indictment in this homicide now stands at $50,000. Anyone with information is urged to call 1-866-411-TIPS. You will never have to give your name."
