Listen up, y’all, lemme tell ya ’bout this fella, Diogo Alves. He weren’t no good, that’s for sure. Born way back when, in 1810, over in Spain. Folks say he come from money, but somethin’ went wrong. He fell off a horse, banged his head, and they started callin’ him “Pancada,” meanin’ “blow.” Guess that blow knocked somethin’ loose in his head, ’cause he turned out real bad.

Diogo Alves, a real bad egg. He come to Portugal, and that’s when the trouble really started. Between 1836 and 1840, this fella, he killed folks. A lot of ’em. Seventy, they say! Seventy souls gone ’cause of him. Can ya believe that? He was sneaky, too. He done his dirty work around the Aguas Livres Aqueduct, so folks started callin’ him the “Aqueduct Murderer.” Scary name, huh? Just thinkin’ ’bout it gives me the chills.
Now, this aqueduct, it was a big ol’ thing, carryin’ water into the city. Perfect place for a killer to hide, see? Diogo, he’d wait for folks, rob ’em, and then… well, you know. He weren’t clean about it neither. Just tossed ’em off the aqueduct, like they was nothin’ but trash. Heartless, that’s what he was.
- Born in Spain: 1810
- Nickname: Pancada (Blow)
- Years of Killings: 1836-1840
- Victims: 70 people
- Killing Location: Aguas Livres Aqueduct
- Known as: Aqueduct Murderer
Folks were scared, real scared. Wouldn’t go near that aqueduct after dark. Can’t blame ’em, can ya? Imagine knowin’ there’s a killer lurkin’ about, waitin’ to snatch ya up. Makes your blood run cold, it does.
But like they say, what goes around comes around. Diogo and his gang, they got caught. Serves ’em right, I say. Seems they got greedy. They went and broke into a doctor’s house, tryin’ to rob him and killin’ folks inside. That was their big mistake. Folks finally caught on, and the law came down on ’em hard.
Justice was served, eventually. They dragged Diogo and his buddies in front of a judge, and there weren’t no doubtin’ they was guilty. The judge, he sentenced Diogo to hang. And hang he did, in 1841. Good riddance, I say. The world was better off without him.

It makes ya think, don’t it? How a fella from a good family could turn so evil. Maybe that blow to the head really messed him up. Or maybe he was just born bad. Who knows? Some folks, they just ain’t right in the head, and there ain’t nothin’ you can do about it. Just gotta stay away from ’em, that’s what I say.
This Diogo Alves fella, he’s a reminder that there’s evil in the world. Gotta be careful, gotta watch your back. Don’t trust strangers, and don’t go wanderin’ around in dark places, especially not near no aqueducts. You hear me? Stay safe, y’all.
Diogo Alves – a name to remember, but not for good reasons. He’s a part of history now, a dark stain on the past. A reminder of the evil that men can do. But he’s also a reminder that justice, even if it takes a while, it usually comes in the end. And that, well, that’s somethin’ to be thankful for, ain’t it?
So there you have it. The story of Diogo Alves, the Aqueduct Murderer. A real bad fella, who got what he deserved. Remember this story, y’all, and be careful out there. The world ain’t always a kind place, and you gotta be smart to stay safe.
Some say he was the first serial killer in Portugal. I dunno ’bout that, but I know he was a killer, plain and simple. And that’s enough for me.

And that, my friends, is the end of that tale. Diogo Alves, the Aqueduct Murderer, gone but not forgotten. A bad memory for Portugal, a lesson for us all.
