The FBI is investigating whether CBP agents went too far when they shot a man multiple times with a Taser at a San Ysidro border crossing, the San Diego Union-Tribune reports. 

Francisco Cesena died after of cardiac arrest caused in part by multiple Taser shots after authorities said he attacked them. According to the federal government, Cesena was wanted on a warrant and attacked agents when they tried to arrest him.

An autopsy revealed seven pairs of puncture marks from a Taser. CBP’s use of force policy bars agents from delivering more than three “cycles” from an electronic weapon.

CBP declined to comment.
