A Mexican man leaped to his death from the border bridge just minutes after being deported from the U.S. for the third time.

Guadalupe Olivas Valencia, 45, was found just yards from El Chaparral, the main border crossing point between San Diego and Tijuana, next to a plastic bag.

His death on Tuesday came on the same day Trump's administration revealed it was tightening immigration laws, meaning almost anyone in the country illegally could face deportation.

Valencia, who was divorced, had been deported back to Mexico just 30 minutes before he took his own life.

Witnesses heard him screaming that he did not want to return to Mexico and that he was going to kill himself moments before he jumped, the BBC reports. He died in hospital a short while later from his injuries.

A plastic bag provided to all deportees by the US border control agency Immigration and Customs Enforcement Agency (ICE), contained a change of clothing and a little food to support the trip back to Mexico.

The 44-year-old was from Los Mochis in Sinaloa - a dangerous northern state which reported 1,938 homicides last month alone.

The soaring rate of homicides, up a third from last year, comes in the midst of a violent power struggle in the notorious Sinaloa cartel since leader Joaquin 'El Chapo' Guzman was extradited to the United States last month.

On Facebook, his family paid tribute to Valencia.

'God has you in his holy glory today,' one relative wrote. 'You left this world, we know that we'll no longer see you physically but in my mind and my heart you will always be present. I know that you're resting in peace. RIP. Condolences for the whole Olivas Valencia family.'

'We will miss you so much, man,' his niece Jennifer Diaz wrote. 'You're an angel from the sky.'

Mexican authorities reported that Valencia had refused to stay in a migrant shelter at the border but accepted food provided by the National Institute of Migration for his journey through Mexico.

Valencia's tragic suicide occurred the same day as two memorandums from the Department of Home Security revealed the government would start an expedited deportation of immigrants captured at US borders, and declared that almost anyone in the US illegally can be deported, regardless of whether they've committed a crime.

Drafts of two memos seen by Reuters vastly widen the scope of Immigration and Customs Enforcement (ICE) agents, potentially affecting hundreds of thousands of people.

One in particular gives them greater discretion over who gets to be deported - and says that anyone in the United States illegally is subject to deportation.

The memos are guidance to instruct agents in the field to implement two executive orders signed by Trump on January 25 that were intended to deter future migration and drive out more illegal migrants from the United States.

The first memo, which says all illegals are subject to deportation, is concerned with internal immigration control.

It orders ICE agents to disregard President Obama's order to focus on criminal immigrants and recent arrivals.

Instead, the order says, they should switch their focus and prioritize migrants who have been charged with crimes but not yet convicted.

It also broadens the scope of ICE powers to determine who should be deported, and says immigrants will not be afforded rights under US privacy laws.

The second memo instructs Customs and Border Protection (CBP) officers to crack down on illegal migration at the border by holding migrants in detention until a determination in their case is made.

The memos have been approved by secretary of homeland security John Kelly and now face final review in the White House.

They are expected to be released to ICE and CBP early next week.

The guidance does leave in place Obama's 2012 executive action that protected 750,000 people brought to the United States illegally by their parents - referred to by Obama's administration as 'dreamers'.

The fate of the policy, known as DACA, has been hotly debated within the White House, according to sources familiar with the discussions.

Trump said in a news conference Friday that DACA was a 'very difficult subject' for him.

Valencia's tragic suicide comes just days Trump's administration issued new immigration guidelines which declared that anyone in the US illegally can be deported, regardless of whether they've committed a crime (Trump signs a separate executive order on February 9)

New memos, being reviewed by the White House, will tell ICE and border agents that all illegal immigrants can be deported, and to focus less on criminal immigrants and new arrivals

One DACA recipient has so far been arrested: Daniel Ramirez, who was detained in Seattle in a raid on his father's house on February 10.

The DoJ says Ramirez has gang affiliations. His lawyers say that is nonsense and he was pressured by agents to falsely admit to being in a gang.

Kelly said in one of the memos that illegal immigration across the US border with Mexico had 'created a significant national security vulnerability to the United States.'

Trump has directed DHS to prioritize the deportation of criminals. But the White House acknowledged Monday that any illegal resident could be deported at any time for any reason.

'Everybody who is here illegally is subject to removal at any time,' White House Press Secretary Sean Spicer said. 'If you're in this country in an illegal manner...obviously there's a provision that could ensure that you be removed.'

He insisted that the goal of the policy was not, in fact, mass deportation. Rather, it codified a system of prioritization.

A poll conducted by Harvard-Harris found that 80 percent of Americans believe that local law enforcement should be required to turn over illegal immigrants they arrest. But many don't want a border wall, dragging down support for Trump's immigration directives

The Department of Homeland Security did not deny any information contained in the draft memos but did not provide further detail.

The memos were first reported on by McClatchy news organization on Saturday.

The same day the memo was issued, a Harvard-Harris poll was released that shows, 75 percent of respondents said they were in favor of ICE hiring more border patrol agents, another mandate of Trump's.

But 53 percent said they did not think the United States should build a border wall, causing 48 percent of voters to disapprove of the immigration order Trump signed addressing both issues, plus the sanctuary cities. Around 80 percent of Americans believe that local law enforcement should be required to turn over illegal immigrants they arrest to the federal government so they can be deported.
