A 28-year-old man was charged Thursday for allegedly stabbing to death his father, a 55-year-old park craft specialist with the East Bay Regional Park District.
Troy Schwenk was found dead inside his home in Castro Valley on Monday.
Christopher Schwenk, who was convicted of felony unlawfully taking a vehicle in 2010, was arraigned in Alameda County Superior Court in Dublin on Thursday afternoon and is scheduled to return to court on Dec. 3 to enter a plea.
Sheriff's deputies found Troy Schwenk lying on the floor of his home in the 19900 block of San Miguel Avenue at about 3 p.m. on Monday, according to the Alameda County Sheriff's Office. Deputies went there to conduct a welfare check requested by East Bay parks colleagues who had not heard from Schwenk, sheriff's officials said.
EBRPD spokesman Dave Mason said Schwenk was a park craft specialist at Lake Chabot.
Sheriff's Deputy Laurina Holt wrote in a probable cause statement that two park district rangers were concerned about Schwenk because he had failed to show up for work and hadn't responded to phone calls and text messages.
Holt said that when deputies, who were accompanied by the park district rangers, arrived at Schwenk's single-story cottage-style home they saw him laying face up in a puddle of blood on the kitchen floor.

The deputies determined that Schwenk had suffered multiple stab wounds and found a bloody knife near him, Holt wrote.
It appeared to the deputies that Schwenk's body had been moved and he had been dead "for quite some time," she said.
The charging documents allege that Christopher Schwenk killed his father sometime between Friday and Monday.
Christopher Schwenk was at the home when deputies arrived at the residence but didn't respond when deputies asked where his father was and "casually walked away from the residence" before the deputies found his father's body, according to Holt.
However, East Bay parks police officers found and arrested the younger Schwenk in that area a short time after his father's body was found, Holt wrote.
When detectives interviewed Schwenk he was unresponsive to most questions and sat "in complete silence with a blank stare," Holt said.
Schwenk also "had absolutely no emotional or verbal response at seeing photos of his brutally murdered father," she wrote.
Schwenk later invoked his right to remain silent, Holt said.
Troy Schwenk lived alone and had "an estranged relationship" with Christopher Schwenk and another adult son, Holt wrote.
