Brandon Judd  president of the labor union  said  Agent Rogelio Martinez  died Sunday of blunt force trauma to the head.
Federal authorities have not yet said how  Martinez  was killed.
Authorities have been searching for witnesses and potential suspects after  Martinez  was killed and a fellow agent was seriously injured. Officials with U.S. Customs and Border Protection and the Border Patrol said in a statement that the pair were âresponding to activityâ near Interstate 10 in Van Horn  Tex.  when they were harmed. The other agent called for help  and other agents provided medical care and took them to a hospital.
Following news that an agent had been killed  President Trump appeared to connect  Martinez âs death to border security and plugged his plans for a border wall on Twitter on Sunday night.
Sen. Ted Cruz (R-Tex.) said on Twitter  without any further explanation  that  Martinez  and the other agent were âattackedâ and he also linked the incident to security on the border with Mexico.

Authorities seized another 200 million yuan in assets from Huang  once known as the "Price Butcher" for GOME's low prices.
 Huang  in his 40s  was named China's richest man in October 2008 with an estimated net worth of 6.3 billion dollars by the Hurun Report magazine.
 He was detained and placed under investigation a month later  and resigned as GOME director and chairman in January 2009. He was held for more than a year without charge  and tried in April in a Beijing court.
 He stood accused of bribing five government officials with 4.56 million yuan in cash and properties from 2006 to 2008  Xinhua reported previously.
 The bribes were offered in exchange for "improper benefits" for Huang's GOME Electrical Appliances Holdings and Beijing Pengrun Real Estate Development Company  a private equity group which Huang headed  the reports said.
 Before his arrest  Huang was revered in the media as a model entrepreneur who rose from nothing by successfully capitalising on China's decades of economic reforms.

Goldsmith Akis Goumas  is currently attempting to replicate the stone in hard wax or burnt clay to understand the movements  shape and size of the handheld tools used.
In tracing the tool marks on the sealstone   Goumas  speculates that the craftsman may have used a rotating wooden lathe with a sharp edge to engrave the stone.
 He  thinks one artisan did the basic  three-dimensional engraving while another completed the secondary work.
"It isn't one craftsman's work because we can see different qualities of dexterity in the synthesis "  he  told CNN over email.
While  Goumas  may soon have answers as to how  it  was fashioned 3 500 years ago  Stocker says we will probably never know how  it  came into the Griffin Warrior's possession.
