What a time to live in San Francisco! 2015 has brought us even more growth and prosperity, skyrocketing property values...and a violent crime rate that continues to rise and rise. We've had a great example of that last datapoint going since Friday, with a once-a-day string of home invasion robberies in SF for the last four days.

8 a.m. Friday, January 30
A 26-year-old resident of a home on the 100 block of Farallones Street answered a knock at her door. Standing before her was a woman in her 30s that the victim first assumed was a city worker. She wasn't.

Instead, the woman put a knife to the victim's throat, made her sit in a chair, and tied her up with extension cords. The woman and a male accomplice then put a towel over the victim's head, then ransacked the residence. They got away with cash, jewelry and cellphones.The victim sustained injuries minor enough that she was able to decline care.

7:30 a.m. Saturday, January 31
When an 85-year-old man answered the ringing doorbell at his home on Diamond Heights street Amethyst Way, no one was there. But when he went back upstairs, he found two men in his house, men who demanded that he and his 79-year-old wife show them what valuables they owned.

The suspects then ran from the house, with the elderly couple's cash, jewelry, tablet, smartphone, and computer. One of the robbers hopped into a four-door sedan that was waiting outside the crime scene, the other stole the couple's car.

5:30 a.m., Sunday, February 1
A 55-year-old woman was sleeping in her apartment on the 300 block of Buchanan Street, which is between Haight and Page Streets, when two men broke in.

One woke her up and punched her in the stomach and head, then the other tied her up and taped her mouth shut. They ransacked her apartment, and stole some cash they found hidden in a closet.

8:50 p.m. Monday, February 2
Two residents of a home on the first block of Ervine Street were held to the floor at gunpoint by one robber while four more ransacked their home, SFPD spokesperson Sergeant Monica Macdonald says.

The suspects, described only as in their late teens or early 20s, got away with two cell phones and a firearm the victims kept in their home.

At publication time, all of the many suspects remain at large, as does all the property (including that couple's car). When reached today, Officer Grace Gatpandan said that police don't believe that any of the robberies are related, and are investigating them separately.
