The father of a 32-year-old woman shot dead in San Francisco allegedly by an undocumented immigrant deported five times shocked a Senate hearing on the government's immigration policies Tuesday when he revealed that illegals with criminal records kill every 12 days.

Jim Steinle, whose daughter Kathryn Steinle died in his arms on popular Pier 14 this month, decried "disjointed laws and basic incompetence" for his daughter's death as they walked together and demanded legislation to bar the release of illegals from jails in so-called "sanctuary cities" like San Francisco.

"Unfortunately due to disjointed laws and basic incompetence on many levels, the U.S. has suffered a self-inflicted wound in the murder of our daughter by the hand of a person who should never have been on the streets of this country," he said firmly.

One of several to testify at the Senate Judiciary Committee hearing chaired by Iowa Sen. Chuck Grassley, Steinle also revealed a shocking statistic of blunder and murder.

"Between, 2010-2014," he said, "121 criminal aliens who had an active deportation case at the time of their release, were subsequently charged with homicide, homicide-related offenses. Think about that, 121 times over the past four years, an illegal immigrant with prior criminal convictions that later went on to be charged with murder when they should have been deported, that is one every 12 days."

Kathryn Steinle was allegedly killed by Juan Francisco Lopez-Sanchez, an undocumented immigrant convicted of seven felonies. He has pleaded not guilty. He was released from a San Francisco jail before the murder despite a "detainer" request from the U.S. Immigration and Customs Enforcement because the city is one of over 300 "sanctuary cities" that ignore ICE demands for access to criminal illegals.

The so-called "Kate's Law" pushed by her parents and championed by Fox News star Bill O'Reilly would declare that "undocumented aliens who are deported and return to the United States would receive a mandatory five year sentence in a federal penitentiary upon conviction."

Said Jim Steinle, "take these undocumented felons off the streets for good."
