Four suspects, including teen boy, arrested in armed robbery of Santa Rosa home

Three Santa Rosa men and a teenage boy were in custody Friday, suspected of barging into a home with masks and at least one gun to demand cash and marijuana from a 16-year-old boy who opened the door, police officials said.

Santa Rosa police gang detectives made the fourth and final arrest late Thursday after a two-week investigation into the Oct. 16 daytime robbery on Luna Court off Bennett Valley Road, Sgt. Tommy Isachsen said.

Detectives think one of the suspects, a 15-year-old Rohnert Park student, knew the victim, and that he and the other suspects thought there would be marijuana and cash at the home because of what the victim apparently posted on social media, Isachsen said.

The suspects found no marijuana or cash during the robbery but rummaged through the house and ran out the door with video game electronics and other items, speeding away in a white American-style sedan, Isachsen said.

Santa Rosa residents Tevris Grayson, 21, Marshaun Wagner- Saxxon, 20, and Nasheem Wehner, 19, and the 15-year-old boy were arrested on suspicion of a variety of felonies, including kidnap with intent to commit a robbery, grand theft, burglary and robbery, as well as misdemeanor brandishing a firearm, police said.

Isachsen said that social media helped detectives connect the suspects to the case, and that they uncovered several replica semiautomatic handguns when they searched the suspects’ homes.

Police arrested the teenager Wednesday at a school in Rohnert Park. Later that day, detectives spotted Wagner-Saxxon and Wehner near their home on Delport Avenue in Roseland and arrested them.

Grayson turned himself in at the Santa Rosa police station late Thursday after detectives searched his two Roseland residences, one on Pebblecreek Drive and the other on Joseph Court East, where detectives found what appeared to be items taken during the robbery, Isachsen said.

Wagner-Saxxon and Grayson were being held on bail amounts exceeding $1 million, and Wehner was being held without bail because he is on felony probation, according to jail records.

The 15-year-old was in custody at juvenile hall.
