Lt. Mike Cook said the stabbings are believed to be gang related but police do not believe the victims are active members of a gang. They were initially believed to be juveniles.
Police responded to a reported fight and found the two stabbing victims at Yarberry and Stillson drives near the school around 9:30 p.m., Cook said.
Both victims suffered multiple stab wounds and were taken to local hospitals. They were listed in serious condition today but are expected to survive, Cook said.
Investigators determined the victims were challenged by another group of young males because they were wearing red clothing. The suspects demanded to know the gang the victims claimed, Cook said.
The victims tried to run from the area but were caught by the larger group of males who left in a vehicle after the stabbings, Cook said.
Police investigated the stabbings through the night and a SWAT unit served a search warrant at a residence in the 500 block of Lakeville Circle around 6 a.m. Tuesday, Cook said.
Gregory Hansen, 19, of Petaluma, tried to hide inside the residence but surrendered after he was warned police dog "Kilo" would be sent inside, Cook said. Hansen was arrested for probation violations and booked into the Sonoma County jail under no bail.
Detectives identified Alan Arbor, 18, of Petaluma as another suspect as he left a residence in the 1800 block of Lakeville Road Tuesday morning, Cook said.
Albor was hiding in the back seat of a car driven by 20-year-old Juliana Padilla, of Petaluma, Cook said. Albor was arrested for attempted murder with gang enhancements after a high-risk stop on U.S. Highway 101 north at Railroad Avenue, Cook said. Albor was booked into the Sonoma County jail under no bail.
Padilla was arrested on suspicion of harboring a fugitive, was interviewed and was released by police, Cook said. Police do not believe she was involved in the assault, Cook said.
Police have not had a chance to interview the stabbing victims and the case is still under investigation, Cook said.
