COVINA — Police arrested a father and his two sons on suspicion of drug sales Saturday after serving a search warrant at their Covina home.

Santiago Saldana, 49, Edgar Saldana, 24, and Erick Saldana, 26, were booked on suspicion of narcotics charges including possession of methamphetamine and cocaine for sales and unauthorized cultivation of marijuana, Covina police Lt. David Povero said.

Police had received complaints from neighbors that possible drug dealing was going on at a home in the 1300 block of North Fenimore Avenue, Sgt. Gregg Peterson said.

Investigators obtained a search warrant and carried it out at the home about 2 p.m. Saturday, the sergeant said.

Inside the home, officials found “significant amounts” of cocaine and methamphetamine, as well as about half a dozen marijuana plants being grown, police said.

Additionally, officers seized a sawed-off shotgun, a rifle and cash from the home, Peterson said. Other pieces of evidence linking the home to drug sales, such as plastic baggies and scales, were also found.

In addition to drug charges, Santiago Saldana was also booked on suspicion of possession of a controlled substance with a firearm, Povero said.

He was being held in lieu of $50,000 bail, while the sons were being held in lieu of $30,000 bail, officials said. They were due to be arraigned Tuesday in West Covina Superior Court.
