TULSA, Oklahoma - Police say a fight between two former roommates Monday evening turns into Tulsa's fifth homicide in two days. 

Officers were called about a disturbance involving guns at the One Eton Square apartments in the 8100 block of East 60th Street just after 8 p.m. 

An anonymous caller described hearing two men arguing, a gunshot and a "thud," as if someone had fallen, according to Tulsa Police Sergeant Dave Walker.

When police arrived, 18-year-old Jakhai Adams opened the door to officers and at first, he hesitated to tell them what happened. 

He eventually told police, 20-year-old Mohammed Tareq was shot to death.  When first responders came in, detectives say they found Tareq's body in a sleeping bag.

"It's unusual behavior for somebody but 18 years old and he just killed somebody so, you know, his behavior is his and he owns it," said Sgt. Dave Walker.  

They took Adams in for questioning and later arrested him on a complaint of second-degree murder.  

Sergeant Walker said the two were roommates but Tareq moved out just a few weeks ago.

"Actually, they considered each other like best friends and brothers but something just spiraled," said Sgt. Dave Walker. 

Police believe others were in the apartment around the time of the shooting, including the person who called 911 and they want to talk to them. 

"I don't know if it's 'I don't wanna snitch' or something along those lines but I think a lot of people just do not want to be involved," said Officer Leland Ashley.

Jakhai was booked into the Tulsa County jail and has a bond of $500,000.  Jail records show he has a court appearance set for August 30th.
