Even dangerous felons sometimes serve short sentences, but Benito Vasquez-Hernandez, 58 — guilty of nothing — has been locked up for nearly 900 days (as of early March) as a “material witness” in a Washington County, Oregon murder case. The prosecutor is convinced that Vasquez-Hernandez saw his own son, Eloy, murder a woman in 2012, and the case is on hold until the victim’s body is found. The judge has given Vasquez-Hernandez two opportunities to leave, both impractical (pay a $500,000 bond or give a video deposition, but he speaks no English, is illiterate in Spanish and, said his lawyer, might be mentally incompetent). Consolation: Material witnesses in Oregon earn $7.50 a day.

The continuing crisis

• The trendy St. Pauli neighborhood in historic Hamburg, Germany suffers its share of uncouth revelers who wander out from nightclubs seeking restroom facilities but too often choose walls of storefronts and private homes, reported London’s The Guardian in a March dispatch. The solution, according to the civic group IG St. Pauli: paint jobs with an “intensely hydrophobic” product known as Ultra-Ever Dry,” which somewhat propels liquid aimed at it right back toward the source by creating an air barrier on the surface. In other words, said an IG St. Pauli official, it’s “pee back” time, and shoes and trouser legs should expect splashes.

• We have “139 frogs, toads, lizards, turtles,” Thayer Cuter told Seattle’s MyNorthwest.com in March, touting her Edmonds, Washington, amphibian rescue shop, especially the heroic job done recently on Rocky, the Texas toad who came with stones in his tummy. “He had to have a lot of enemas (but) Rocky is rock-free now” and, after passing all the pebbles, is finally able to eat. Added Cuter, turtles are underrated pets, “very social” and love massages and “cuddl(ing).”

• The Job of the researcher: Cockroaches can be bold explorers or shy and withdrawn, according to recent work by researchers at Belgium’s Universite Libre de Bruxelles, who caught a bunch of them, affixed radio tags and studied their movements. “Explorers” are necessary for locating food sources, although, obviously, they are also most likely to find Roach Motels; “shy, cautious” roaches are necessary for survival and group stability, and a mixture of the types ensures cockroaches’ legendary survivability. A Mother Nature News commentator wrote, hopefully, that understanding roaches’ personalities might make us “less quick” to “grab a shoe.”

Can’t possibly be true

• Ranson IB Middle School in Charlotte, North Carolina, has a strict dress code (requiring, for example, only “hunter green” outerwear). Thus, on Jan. 27, when parent Chanda Spates dispatched her three kids in improperly hued coats, Ranson officials confiscated the “contraband” clothing, leaving the three (along with 20 other sartorial miscreants) to make their way home after classes with no outerwear at all — though the temperature that afternoon was in the 30s. (Following parental outrage, the administrators apologized.)

• A female teacher working for the Arizona Department of Corrections was brutally assaulted in prison by a sexual predator and has sued the department, but in February the state attorney general’s office, contesting the lawsuit, told the judge, basically, that the teacher understood all along that she could get attacked in prison. She was administering inmates a GED exam, but that day had no guard support, not even one to hear her screams, and was given an emergency radio tuned to an unmonitored frequency. Nonetheless, Assistant Attorney General Jonathan Weisbard essentially shrugged: “The risk of harm, including assault, always exist(s) at a prison like Eyman.”

Compelling explanations

Clueless in Florida’s Panhandle: (1) Debra Mason, 58, was arrested for theft of a pickup truck in Destin, Florida, in January — and according to police, Mason said she knew it was stolen property but “didn’t think it was ‘that’ stolen.” (2) Ten miles away in Mary Esther, Florida, in February, Robert Pursley, 54, was arrested for DUI and was asked about items in his truck. According to the police report, Pursley insisted that everything
