A fifth man has been found dead in Lady Bird Lake in Austin, Texas, in the past six months, according to police in the Texas capital.

His identity was not immediately available.

"This case is still under investigation," a department spokesman told Fox News Digital Wednesday. "No further details are available at this time."

Four other men have turned up dead in the lake, which is actually a portion of the Colorado River running through downtown Austin, according to authorities. They have repeatedly downplayed speculation that a serial killer may be behind the deaths.

"If there was any immediate public safety concerns, we would release that information, right," Austin police Sgt. Lee Knouse told FOX 7 Austin Tuesday evening, adding that none of the deaths have been linked to one another.

However, even as the city is increasing safety measures in the area of Lady Bird Lake and along the popular nightlife on Rainey Street, police have reiterated that they have not seen signs of a serial killer, or even foul play.

Then, it turned out the city did have an active serial killer, according to prosecutors – but he had nothing to do with the bodies in the water.

Raul Meza Jr. shot a man in 1975, killed a girl in 1982 and allegedly confessed to two new murders earlier this month as Texas police continue to eye him in other cold cases.

The U.S. Marshals arrested the 62-year-old ex-con in connection with the May murder of his former roommate, an 80-year-old retired probation officer named Jesse Fraga, and in the 2019 murder of 66-year-old Gloria Lofton.

On May 20, he allegedly strangled Fraga with a belt, stabbed him and severed his spine – prompting a manhunt that ended with the suspect apparently calling police and turning himself in.

"I think you are looking for me," Meza said in a May 24 phone call, according to the Marshals.

"I can't say that this guy did anything at Lady Bird Lake, and I can't even say for sure there is a serial killer at Lady Bird Lake – but what it looks like to me is that there are suspicious deaths at Lady Bird Lake," criminal profiler John Kelly said after Meza's arrest. 

The Lady Bird Lake deaths have involved men in or around their 30s who had been drinking on Rainey Street and were later found dead in the water. However, police have said they do not suspect foul play in any of them.

Police found Jason John, 30, dead in Lady Bird Lake in February, a week after he was last seen on Rainey Street, which has a popular row of bars near the water. According to an autopsy report obtained by Fox News Digital, a "transient bystander" witnessed him stumble into the water.

The bystander called 911, but John's remains were not recovered until eight days later. The toxicology report found alcohol in his system and his death was ruled an accidental drowning. 

John's autopsy is the first of the deaths there this year to have been made public.

Clifton Axtell, 40, was identified as the man found dead in the same stretch of water on March 5. Jonathan Honey, 33, was found on April 1, a day after he was last seen at a food truck on Rainey Street. John Christopher Hays-Clark, 30, was also discovered in April, washed up near a dam about two miles down river from where the others were found.

Authorities have increased safety measures around Rainey Street and the Lady Bird Lake waterfront, adding fencing, lighting and increasing patrols to prevent people from slipping into the river. However, some have questioned whether "roofies" or other incapacitating drugs have been used in connection with the deaths.

"If it turns out that we believe there's a serial killer at Lady Bird Lake, then what are the odds we have two serial killers in the same city?" Kelly, the criminal profiler, asked.

EXCLUSIVE - Focus on the Family's recent pro-life campaign ad challenged perceptions about the terminology often used to describe unborn babies, and it hit a noticeable nerve with viewers. 

The faith-based organization launched its "It's a Baby" ad last week ahead of the one-year anniversary of the Dobbs v. Jackson Women's Health Supreme Court ruling that overturned Roe v. Wade and gave states back the power to decide their abortion laws. The campaign featured parents celebrating pregnancy by declaring, "We're having a fetus!" or "You want to feel the fetus kick?" Its intent, Focus on the Family President Jim Daly said, was to challenge long held perceptions about abortion and the preborn.

‘WE’RE HAVING A FETUS!' PRO-LIFE AD CAMPAIGN CHALLENGES PERCEPTION OF UNBORN BABIES

The campaign has driven millions of people to their corresponding website, Daly said the group's ad agency relayed. 

"It's really important to get the language right because the one thing that oftentimes the pro-life community is accused of not being sensitive or caring for the mom, and that's just absolutely untrue," Daly told Fox News Digital. "So I think the maturity of the pro-life movement has arrived." 

Daly said the ad effectively broke down the right to life debate in the simplest terms.

"They're just normal terms," he said. "When a woman's pregnant, she has that baby bump. That's what we refer to the baby as - it's a baby. And I think that was the beauty of the ad, just to make it stated as simply as we can once again, that it's a baby. And I think most people agree with that."

Daly detailed some of the work he and his colleagues have done for expectant mothers, which he said undermines the argument that the pro-life movement is insensitive to mothers struggling with unplanned pregnancies.

"There's ample support for women through the pregnancy resource centers who are struggling financially or with job training issues or job placement issues," he said. "There's so much going on right now to support a woman who has an unplanned pregnancy. We're the other option. We think taking the life of the child is not the right option. So the pro-life community is doing everything it can to support a woman with very difficult choices."

While Dobbs gave pro-lifers a reason to celebrate, Daly said their fight is far from over.

"We needed that step in the pro-life community to further the care of the pre-born child and his or her mother," Daly said. "But now the fight goes to all 50 states."

Dobbs opponents like First Lady Jill Biden argue that the ruling was "devastating" for women.

"The Dobbs decision was devastating," Biden said at a White House event with four women who said they'd been negatively impacted by the decision. "The Dobbs decision took away women's constitutional rights, their ability to make their own healthcare decisions."

Daly said his faith-based organization is trying to convince those Americans in the middle on the abortion debate that the preborn child is a baby. 

"One of the things we're working on is adoption options. I think we're the first group in the country to try to develop a national adoption list, parents waiting for an infant child adoption. So we're looking forward to developing that along with 800 adoption pregnancy centers, etc."

Daly shared his personal reason for having originally joined the pro-life movement. His father, he explained, talked his mother out of having an abortion in California in the 1960s. 

"For me, even before Roe v. Wade, my mom was 42 in California, and you could get an abortion even then," Daly said. "That was in the 60s. And so I'm actually an abortion survivor in that my father talked her out of it. I was the seventh child of a very poor family. And my mother didn't think financially they could do it. And my dad told her, no, we can't do that. We can't have an abortion." 

"So, you know, directly a benefit of a pro-life perspective," Daly continued. "And my life has not been easy. I ended up an orphan child. But for anybody that says that a poor child should not be born because of the status of their financial situation and the direct opposite, I mean, I achieved it. I made it. And I think every child should have that chance."
