The victims have been identified
as 23-year-old twin sisters Rebeika Powell and Kayetie Melchor, 33-year-old Misty Nunley and 56-year-old Julie Jackson. Their bodies were discovered inside a unit at the Fairmont Terrace Apartments at East 61st Street and South Peoria Avenue. A terrified 4-year-old boy was also found unharmed in the apartment.
Tulsa police are searching for the shooter.
"Right now we have no clear-cut suspect we're looking at at this point," police spokesman Leland Ashley told reporters
on Monday evening. "I don't want to strike fear in the community tonight, but we do have an individual or individuals who have murdered four people. Do we know if there was a motive, like a jealous lover? We don't know that. We can't say if it was random, or if someone knew (the victims).
Ashley told reporters that detectives were "beating the bushes" to find whoever committed the murders.
Police say the shooting, which took place in a run-down part of the city near the Arkansas River, occurred between 11:30 a.m. and 12:30 p.m. Police received a 911 call around 12:30.
Neighbor Sennie Anderson, who has been living in the Fairmont Terrace complex for two years, told the Associated Press that crime there "is getting worse."
"I've been afraid since I moved in this place," she said as she held her crying 3-year-old daughter.
Last September, Fairmont Terrace, considered one of the city's most dangerous apartment complexes, was the site of another murder when 20-year-old Robert Max Long
was shot dead. In the wake of that killing, Tulsa police met with the complex's management staff to offer suggestions on how to reduce violent crime.
"We suggested everything from lighting to preventing non-residents from entering the property-- their electric gate, the fencing around their facility, monitoring who the residents have as far as visitors and things like that," TPD gang unit Sgt. Sean Larkin told
NBC 2 reported that there are still no security cameras monitoring the complex.
"Honestly, if security cameras were installed, this probably wouldn't have happened," longtime resident Tyler Smallwood told an NBC 2 reporter.
Tulsa is still coming to terms with a shooting spree in which two white men allegedly targeted black residents
, killing three and wounding two others last April. Prosecutors are seeking the death penalty for accused shooters Jacob England and Alvin Watts.
