Police are now asking for the public's help to figure out what happened to Zachary Rose.
Here's part of NBC Bay Area's report:
Rose left work at 5:37 p.m. Friday, Feb. 2, after telling (co-worker Joe) Poplete he planned to spend Super Bowl weekend playing piano, according to investigators. Police say they have security footage and bridge-crossing photos that confirm he drove his pickup from Bio-Rad to Fairfield, where Lasater lives on Shorey Way. The two had met online, and in 2015, Rose left his native Arkansas to move in with Lasater, according to Robyn Rose. But by the time Rose disappeared, he had leased his own apartment in Hercules.
Investigators say Lasater reported Rose missing 17 hours after he said he last saw him at 10 p.m. Feb. 3. In a dispatch call obtained by NBC Bay Area, an emotional Lasater is heard telling a dispatcher how Rose had left the house the night before, leaving behind his parked truck and all his personal belongings, and had not returned. He said he wasn’t aware of anyone with whom Rose might have left.
As police began to probe Rose’s disappearance, they were reminded of the 2012 unsolved death of Lasater’s husband of 15 years. Bill Volkl, 41, died unexpectedly, apparently in his sleep. But the Solano County medical examiner was not able to determine what caused his death.
Volkl was obese and had a history of heart problems but also suffered an unexplained neck injury. “Our office cannot rule out foul play,” in light of that injury, the report noted.
Jacobsen says the two unsolved mysteries have police stymied.
