A manslaughter investigation has been launched into the deaths of seven people in the sinking of a luxury yacht off the coast of Sicily, an Italian prosecutor said.

British tech mogul Mike Lynch and his 18-year-old daughter Hannah were among the seven people who died after the Bayesian superyacht sank near Porticello at about 5am local time on Monday.

Ambrogio Cartosio, public prosecutor of nearby town Termini Imerese, said in a press conference at the town’s court on Saturday that his office has opened an initial investigation into manslaughter.

“The Termini Imerese prosecution has opened a case hypothesising the crime of shipwreck and of manslaughter but we are only at the initial stage of the inquiry so far,” he said.

He added: “I have to emphasise that the development of the inquiry could actually be of any sort imaginable.”

The main question investigators are focusing on is how a sailing vessel deemed “unsinkable” by its manufacturer, Italian shipyard Perini Navi, sank while a nearby sailboat remained largely unscathed.

In the 1870s, Irish farmers faced an agricultural crisis that threatened to result in a repeat of the terrible famine and mass evictions of the 1840s. Anticipating financial ruin, they formed a Land League to campaign against the rent increases and evictions landlords were imposing as a result of the crisis. When retired British army captain Charles Boycott, acting as an agent for an absentee landlord, tried to evict tenant farmers for refusing to pay their rent, he was ostracized by the League and community. His laborers and servants quit, and the crops in his care began to rot. Boycott’s fate was soon well known, and his name became a byword for that particular protest strategy, both as a verb and as a noun.

Harley-Davidson was 'one of the backbone companies of America,' Lanckiewicz says in his first video.

'But the unthinkable has happened — they've gotten a woke CEO who's trying to do everything he can to change this company, not for the better, but for their own woke agenda.'

The way Lanckiewicz tells it, DEI amounts to 'communism' and is linked to satanic forces that are hell-bent on destroying America.

'They're going to put somebody in a position because of the race, gender, not because who's the most qualified for the job. That's crazy,' he says.

Then, Lanckiewicz and his friends unload on two Harleys — an Electra Glide and a Sportster — with an increasingly ferocious arsenal of weapons.

The automotive carnage starts with M60 machine guns before moving on to an M134 mini-gun, and then two powerful 50 BMG rifles.

In the second video, the men cause more damage with a 6lb cannonball fired from a 'historic' piece of artillery.

For a finale, the men add Bud Light cans and a Target bag to the bikes — emblematic of two other major firms that were boycotted last year over alleged wokery.

They're dressed in 'patriotic' fatigues from the 1775-1783 war for independence from Britain.

'Mr woke CEO of Harley-Davidson, your anti-American wave will no longer be tolerated, and I've got 6lbs of American patriotism going at your woke pile of c**p,' says Lanckiewicz.

The videos have been watched hundreds of thousands of times and won plaudits from viewers, including Robby Starbuck, the conservative influencer who started the crusade against DEI at Harley-Davidson and across corporate America.
