Only one employee managed to escape when Zephen Xaver, 21, allegedly walked into a Suntrust bank and opened fire.

All five victims gunned down inside a Florida bank Wednesday were women and were killed execution-style.

Zephen Xaver, 21, walked into a Suntrust bank branch in Sebring Florida and within six minutes made all the women lie down on the ground and shot them in the back of the head, according to police and court documents cited by the New York Post reported.

Bank employees Marisol Lopez, 55, Ana Pinon-Williams, 38, and customer Cynthia Watson, 65, have been identified amongst the victims, according to a Florida Today report. Two other female employees, ages 54 and 31, were also killed. Their names have not yet been officially released.

There was one survivor, a bank employee who was able to flee, according to Florida Today. Previously, it was reported that there were no survivors. The name or gender of that survivor has not been released. However, law enforcement did disclose that the survivor was in a back break room when shots rang out. They then ran out a back door, according to ClickOrlando.

After allegedly killing the women, Xaver called 911 from inside the bank and told them, “I have shot five people.”

He was armed with a handgun and wore a bulletproof vest, according to that affidavit. Xaver then barricaded himself inside. When negotiations failed, the SWAT team burst in, capturing Xaver and discovering the bodies, police said. Investigators have not offered a possible motive, but they said they don't think it was a robbery-gone-bad. Xaver has no apparent ties to the bank or the victims.

Xaver, originally from Indiana, has long been fascinated with the idea of killing, but people who could have done something about it didn't take his threats seriously, Alex Gerlach, who identified herself as a former girlfriend told WSBT-TV in South Bend, Indiana.

Florida Department of Corrections records show that Xaver was hired as a trainee prison guard at Avon Park Correctional Institution on Nov. 2 and resigned Jan. 9. No disciplinary issues were reported.

Xaver lived in a non-descript pre-fabricated home about four miles from the bank. No one answered the door Wednesday night after police finished searching the home. John Larose, who lives next door, said Xaver kept to himself, but he could hear him playing and yelling at video games in the middle of the night.

He has been charged with five counts of capital murder. He was ordered held without bond.

At a Thursday press conference, Tim Williams, brother-in-law of victim Ana Pinon-Williams, vowed to not let his relative be defined by the tragedy.

"We are determined to let Ana’s memory be marked by the life she lived, the people she loved, and the difference she made," he said.

Florida is flying their flags at half-mast a response to the murders.
