OKLAHOMA CITY -- Police make a big break in murder investigation dating back to last year.
Seven months ago, in late October, a 19-year-old girl was found shot to death at a friend's apartment in southwest Oklahoma City.
This week two people have finally been arrested in connection with the shooting.
Both suspects remain behind bars in Cleveland County.
One person who knew the victim confirmed the suspects and the victim had been friends leading up to the murder.
The shooting happened at an apartment complex on S.W. 89th St. where police first found 19-year-old Kelsey Bransby.
"Officers were called on a disturbance and found her inside and shot," OKC Police Capt. Dexter Nelson.
The victim died a few days later.
For several months, police had few leads and no suspects were ever named.
Until this week, when police arrested two people, 20-year-old Cole Hopper and 19-year-old Danielle Cooley.
"It's always good to take a homicide case off the books. You don't like to have 'em hanging over your head," Nelson said.
One of the people who first found the victim's body inside the apartment claims the victim had been best friends with the female suspect, Cooley.
Right now police can't confirm what sparked the deadly shooting.
"The detectives have interviewed the two arrested suspects," Nelson said. "The statement of those two have not been made public. I don't know what the relationship is or could have been between the arrested and the victim."
In a tragic coincidence, the victim in this case attended Mustang High School in the same grade as Carina Saunders.
Saunders was found murdered last year, her body dismembered and stuffed in a duffel bag.
Police said the two cases don't appear to be related.
