Analysis of cell phone data, video and scientific evidence led to murder charges in the Aug. 17 shooting outside of The Cobra bar in East Nashville that killed two people and set the city on edge, authorities said Friday.

Indictments from the Davidson County grand jury were unsealed Friday, charging Demontrey Logsdon, 20, and Horace Williamson III, 27, with first degree murder and especially aggravated robbery.

The 20-count indictment included several additional charges related to other alleged crimes. Williamson and Logsdon also were charged in an Aug. 17 kidnapping case.

The men were in custody on other charges when the indictments were released. Metro Det. William Ashworth said he did not believe any other suspects in the homicides were at large.

"This has been hard on East Nashville and Davidson County in general," Ashworth said. "I hope at this point they're able to find some sort of solace."

Police did not say what motivated the Cobra shooting but Metro Det. Chad Gish said police had "reasons to believe that maybe there was reasons other than robbery."

A third suspect, Lacory Lytle, 24, was indicted on charges of identity theft and fraudulent use of a credit card that was taken from the Cobra shooting.

The indictments came more than a month after police announced the three men as people of interest in the case. Police said they had spent "hundreds of hours" building their murder case, including tracking location data on the suspects' cell phones and reviewing surveillance footage.

Investigators said surveillance videos showed both Logsdon and Lytle using credit cards taken during the Cobra robbery.

Police did not discuss additional evidence in detail, but Ashworth said the investigation was "not close to being done."

Police said Logsdon and Williamson robbed four people around 3:30 a.m. Aug. 17 outside The Cobra bar on Gallatin Avenue. Investigators said they shot and killed two of the robbery victims: Bartley Teal, 33, and Jaime Sarrantonio, 30.

Williamson also was charged with aggravated sexual battery. Police said he fondled Sarrantonio and one of the surviving robbery victims.

The shooting rocked the community, particularly after investigators linked it with a series of other seemingly random shootings in August, including the Aug. 14 shooting death of Kendall Rice, 31.

No charges have been issued in those cases. Police did not comment on the progress of those investigations but said they remained open.

District Attorney Glenn Funk praised police and prosecutors in a statement, saying they worked together to "obtain indictments in a senseless double murder that took two innocent lives, and shook the security of an entire community."

"I believe our community can feel a further sense of relief now that the two have been formally charged in the Cobra case," police Chief Steve Anderson said in a statement.
