(CNN) - Nashville police were holding two men Monday night who were wanted for questioning in shootings that left three people dead.
Officials said they took Demontrey M. Logsdon, 20, into custody at a Nashville residence, and Lacory C. Lytle, 24, turned himself in at a precinct.
Logsdon was arrested on an outstanding warrant for aggravated kidnapping. Police say he accompanied another man who kidnapped a woman on Friday.
Lytle had outstanding warrants charging him with felony identity theft, fraudulent use of a credit card, and theft for using a stolen credit card of a victim who survived a robbery that killed two people.
The men have not been charged with any of the killings, which police say are still under investigation.
Three killings were during robberies
Two men traveling in a dark-colored Chevrolet shot the victims as they walked down a street or stood in a parking lot in the early morning, according to police. All three killings happened during robberies, authorities said.
About 3:30 a.m. Friday, Bartley Teal, 33, and Jamie Sarrantonio, 30, were fatally shot in the parking lot of the Cobra bar on Gallatin Avenue in East Nashville, police said in a news release.
They had left the bar with two other people, walked to a convenience store for snacks, and were returning to the bar when the two men confronted them in the parking lot, Aaron said at a news conference.
"Mr. Teal was told that it was a robbery," Aaron said. "He reportedly said he had nothing to give. He was then fatally shot."
Sarrantonio was shot a few moment later for unknown reasons, Aaron said.
"Detectives believe the murderers ... were randomly looking for robbery victims and targeted the four when they arrived back at the Cobra parking lot," police said in a Friday news release.
Sarrantonio and Teal died after being taken to hospitals. The two other people were not hurt. The robbers drove away and dumped the victims' belongings in an alley in north Nashville, police said.
The double murder appears to be connected to another killing that occurred a few days earlier, police said.
On August 14, Kendall Rice, 31, was shot about 4 a.m. while walking along Alta Loma Road to catch a bus to work at Vanderbilt University Medical Center, Aaron said.
"According to a witness, two black men who appeared to be in their 30s, shot Rice and fled in a dark sedan," police said in a news release. "Rice died at the scene. His personal belongings were missing."
More crimes might be linked
Other robbery attempts happened August 14 that may be connected, police say.
At 4:45 a.m., a man said he drove off after two men -- one armed with a rifle -- tried to rob him at the Rivergate Meadows Apartments on Rivergate Meadows Drive, police said. At 5:15 a.m., a man was shot and critically injured during a robbery attempt at an apartment complex on East Palestine Avenue.
These shootings may also be linked to the August 8 shooting of a woman in the Inglewood neighborhood, Aaron said.
The Tennessean newspaper said the woman, 39, was walking her dogs a little after midnight when two men driving by in a small, dark car shot her. She apparently was not robbed. The woman was wounded in the back, the newspaper said.
"We obviously have to consider the August 8 case as we pursue active leads in the two homicide cases," Aaron said.
Lytle was convicted of felony aggravated assault in May. Logsdon was convicted of robbery in November. Both received five years probation.
Police were looking for them based on surveillance images, recovered evidence and observations by officers.
