The FBI in Houston also released new photos of the accused on Sunday.

The manhunt continued on Sunday, more than 24 hours after 38-year-old Francisco Oropesa gunned down five people, including a minor.

Oropesa is in the country illegally and has been deported previously, an ICE source told Fox News Digital.

He has re-entered the U.S. illegally "multiple" times and ICE last encountered him in 2016, the source said.

FBI tweeted: "Here are the newest images of Francisco Oropesa and a prominent tattoo on his left forearm. Going forward, the subject's last name will be spelled 'Oropesa' to better reflect his identity in law enforcement systems. This remains a fluid investigation."

FBI Houston Special Agent in Charge James Smith announced there’s now also a collective $80,000 reward being offered for information that leads to the suspect’s arrest.

“We don’t have any tips right now to where he may be and that’s why we’ve come up with this reward, so that hopefully somebody out there can call us,” Smith said at Sunday’s news conference as quoted by CNN.

“I can pretty much guarantee you, he’s contacted some of his friends,” Smith said, adding, “We just don’t know what friends they are and that’s what we need from the public, is any type of information because right now we’re running into dead ends.”
