5 Arrested at House in Lancaster : Crime: Deputies responding to a call about a loud party find a pipe bomb, sawed-off shotgun and drugs.

Three adults and two teen-agers were arrested after sheriff’s deputies found weapons and drugs at a Lancaster house during a routine call about a loud party, authorities said Sunday.

Los Angeles County sheriff’s deputies reported discovering a homemade pipe bomb, a sawed-off shotgun and unspecified amounts of methamphetamine and marijuana about 9 p.m. after they responded to a neighbor’s complaint of a loud party in the 44000 block of 40th St. West.

Scott Shows, 21, who lives at the house, was arrested on suspicion of possessing controlled substances, a sawed-off shotgun and an explosive device, said Lt. Daniel Castillo of the Antelope Valley Sheriff’s Station. He is being held in lieu of $500,000 at the station’s jail, he said.

Penny Bowen, 24, of Quartz Hill, and Marjorie Richardson, 29, of Palmdale, were arrested on suspicion of being under the influence of a stimulant, Castillo said. Bowen was cited and released. Richardson is being held on a previous warrant. Her bail is set at $3,500.

Two 16-year-old girls from Palmdale and Quartz Hill also were arrested on suspicion of being under the influence of illegal drugs, Castillo said.

“We were called there to tell them to turn down the loud music,” Castillo said. “It was a routine party call until we found the pipe bomb.”

When deputies arrived at the house, a couple of party-goers ran from the scene, Castillo said. While they spoke with one of the minors arrested, deputies noticed expended .22-caliber rifle casings in the front yard.

“They conducted a search of the house and noticed the shotgun and white powdery substance and the marijuana,” Castillo said.

In a more in-depth search, they found the pipe bomb and evacuated the house until bomb squad investigators could dispose of it, he said.

An investigation is continuing, Castillo said.
