In 2015, Kate Steile was killed by an illegal alien who had been deported five times prior to this crime and had a lengthy criminal record; San Francisco’s status as a well-known sanctuary city is believed to have contributed to the senseless murder.

Kate’s relatives are now filing suit.

Fox News reports:

Relatives of the woman shot to death on a San Francisco pier last year filed a lawsuit Friday saying the illegal immigrant accused in the killing should have been in custody if not for a series of mistakes by city and federal workers.

. . . .  The sheriff at the time of the killing, Ross Mirkarimi, is named in the lawsuit, along with ICE and the Bureau of Land Management. Mirkarimi previously defended the release of the suspect, a repeat drug offender and habitual border-crosser.

Frank Pitre, the lawyer for Steinle’s family, said the lawsuit points out “failures at every level.”

“We’re approaching the one year anniversary of Katie’s death and it is a particularly difficult time for the family.”

He said a seven-time convicted felon was able to obtain a BLM officer’s handgun due to negligence and ICE agents did not pursue his deportation.

According to a USA Today report last year, Kate’s murderer had recently been released from prison when he walked up and shot Kate as she strolled on a waterfront pier with her father and a family friend.

Francisco Sanchez, 45, a Mexican citizen deported from the United States five times and only recently released from U.S. prison after again getting caught sneaking into the United States, admitted Sunday he accidentally shot Kathryn “Kate” Steinle, 32, on July 1 as she walked on San Francisco’s Pier 14 with her father and a friend.

The San Francisco District Attorney on Monday charged Sanchez with murder, and he’s set to be arraigned Tuesday afternoon.

Federal officials say he should have never been walking the streets a free man. Federal officials released Sanchez in March from federal prison where he had served nearly four years for previous immigration violations. They delivered Sanchez to the San Francisco sheriff’s office, where he was wanted on felony marijuana distribution charges. Local officials dropped those charges a few days later and released Sanchez onto the street despite a request from U.S. Immigration and Customs Enforcement to detain him for deportation.

“As a result, an individual with a lengthy criminal history, who is now the suspect in a tragic murder case, was released onto the street rather than being turned over to ICE for deportation,” said Gillian Christensen, an ICE spokeswoman, said Monday.

The requests, known as “detainers,” ask local law enforcement to notify ICE agents before they release a convicted criminal with a history of immigration violations.

“We’re not asking local law enforcement to do our job…all we’re asking is that they notify us when a serious foreign national criminal offender is being released to the street so we can arrange to take custody,” Christensen said.

Earlier this week, San Francisco upheld its illegal status as a “sanctuary city.”

Fox News reported Wednesday:

Despite national outrage after a Mexican man killed a woman along a waterfront pier, San Francisco officials upheld the city’s strict sanctuary protections for people who are in the country illegally.

The Board of Supervisors voted unanimously on Tuesday for a measure that clarifies when city workers, including police officers, can notify Immigration and Customs Enforcement of a person’s immigration status. Generally, the defendant must be charged with a violent crime and is someone who has been convicted of a violent crime within the past seven years.

The measure, however, also grants San Francisco’s sheriff leeway to contact immigration authorities in the limited cases of defendants charged with a felony if they have been convicted of other felonies in the past.
