TEMECULA - Authorities today held a 29-year-old Temecula man suspected of using a hammer and a wrench in an assault on his mother and 10- year-old brother while high on drugs, then holding sheriff's deputies at bay.

Deputies went to the 31100 block of Tecumseh Court around 6:10 p.m. Monday after the boy called authorities to report that he and his mother had been attacked by Aaron Graves inside their home, said Riverside County sheriff's Sgt. Curt Harris. When deputies arrived, Graves barricaded himself inside the home and threatened to assault anyone who approached him, he said.

Deputies entered the home through a rear patio door, but Graves refused to drop his weapons and surrender, Harris said. He was then zapped with stun guns, but they had no effect, prompting deputies to shoot him with a pepper ball device, he said.

The suspect was momentarily disabled, but deputies were still not able to take him into custody, according to Harris, who said deputies then unleashed a police dog that Graves tried to hit with a hammer. While Graves was engaged with the dog, deputies moved in and took him into custody, he said.

Two deputies suffered minor injuries during the encounter, according to Harris.

"Subsequent examination of Graves indicated he was under the influence of a controlled substance," Harris said.

Paramedics treated the woman and boy at the scene for minor injuries, he said.

Graves was taken to a hospital for treatment of injuries and, once discharged, was booked at the Southwest Detention Center in Murrieta, Harris said. He was facing possible charges of assault with a deadly weapon, willfully harming a child, resisting arrest and removal of a telephone or electrical line, according to sheriff's online jail Advertisement

Graves was being held in lieu of $35,00 bail with a court appearance scheduled for Friday in Murrieta, according to the sheriff's department.

Man arrested after assaulting mother and 10-year-old brother with hammer and wrench

TEMECULA - SHERIFF PRESS RELEASE - On February 11, 2013, at around 6:10 pm, police officers from the Temecula Police Department and deputies from the Riverside County Sheriff's Department arrived at 31100 block of Tecumseh Court, Temecula, CA, after a ten-year-old child made an emergency call for help. When officers arrived, they learned twenty-nine-year-old Aaron Graves had physically assaulted his mother and his ten-year-old brother with a hammer and wrench.

When officers encountered Graves at the house, he initially barricaded himself inside and threatened to physically assault anybody who approached him. Officers made entry into the house through a rear patio door, but a standoff ensued. Graves refused to comply with the officers' requests and demands to drop his weapons.

Officers subsequently deployed their Taser devices, but they were ineffective. Officers then deployed a Pepper Ball device, which momentarily disabled Graves, but he quickly re-engaged law enforcement. Officers then deployed a department-trained K-9 to subdue Graves. Graves resisted and attempted to strike the K-9 with a hammer. When he engaged the K-9, officers quickly subdued Graves and placed him in handcuffs, but only after two officers suffered minor injuries during the incident.

Subsequent examination of Graves indicated he was under the influence of a controlled substance. His mother and young brother were treated by paramedics at the scene, but their injuries were minor. Graves was treated and released from a local hospital and booked at the Southwest Detention Center.

Anybody with information in this matter is encouraged to contact the Temecula Police Department at (951) 696-3000.
