Not sure if any of this is connected, but it certainly is quite a coincidence. We note three stories on three consecutive days:
♦ Sunday, May 8th – “Sickening new pictures have emerged of a new form of ISIS execution – stabbing prisoners directly in the heart to kill them for their ‘crimes against the caliphate'”. (link)

♦ Monday, May 9th – GRAFING, Germany — A German man yelled “infidel, you must die” and “Allahu akbar” as he stabbed one person to death and wounded three others at a Bavarian train station Tuesday, but authorities said they’ve found no links to any Islamic extremist network. (link)
♦ Tuesday, May 10th – (last night) BOSTON – TAUNTON (CBS) – An off-duty officer shot and killed a man who allegedly stabbed two people to death during a rampage at two locations in Taunton Tuesday night.

Police responded to the Silver City Galleria shopping mall just before 7:00 p.m. after the suspect, identified as 28-year-old Arthur DaRosa, crashed a black Honda Accord into the entrance of a Macy’s store.
“We saw the car just like dove right in,” a woman said. “It honestly happened like the fastest thing.”
Moments later, police say DaRosa exited his car, assaulted multiple people inside Macy’s, and then walked into a Bertucci’s restaurant inside the mall. Inside the restaurant, DaRosa allegedly stabbed multiple people including a 56-year-old man who died. DaRosa was shot and killed by an off-duty Plymouth County sheriff’s deputy inside the mall.
One of the victims who was attacked at the mall was a pregnant woman, a witness told WBZ.  (read more)
