An anonymous tip helped deputies arrest three suspects in a Halloween night home invasion and put them on the trail of a fourth suspect.
Wednesday, Citrus County sheriff's detectives arrested Michael Ingram, 19, Pedro Velez, 17, and Jonathan Velazquez, 16, and charged each of them with one count of home invasion-robbery.
Detectives are looking for 21-year-old Frederick "Fred" Addison. His last known address was the Atlantis Arms Apartments in Crystal River.
Authorities have accused Addison of holding down 69-year-old Madelaine Cook after four men forced their way into her Crystal River home and made her reveal where she kept her cash, then searched for other valuables.
"He's the one who grabbed her and held onto her while the other three went through the rest of the residence looking for cash and property," sheriff's spokeswoman Gail Tierney said.
Cook told deputies she and her 7-year-old grandson thought it was another group of trick-or-treaters knocking at the door about 10 p.m.
Instead, four black-clad men forced their way into the home, Cook said. Two of them wore stockings over their heads; two wore black handkerchiefs. All wore gloves.
Cook and her grandson were not injured. Cook told deputies she thought two of the robbers had visited the residence earlier looking for Halloween candy.
At first, Cook thought the suspects got away with about $50 from her purse, but detectives recovered about $400 worth of jewelry.
Detectives arrested Ingram and Velez at the Atlantis Arms complex about 11 p.m. Wednesday. Deputies picked up Velazquez in the Homosassa area earlier that night.
Ingram, of 936 NE First St. in Crystal River, was booked into the Citrus County jail, where he is held in lieu of $50,000 bail.
The two juveniles arrested in the case _ Velez, of 9755 W Arms Drive in Crystal River, and Velazquez, of 17 N Washington St. in Beverly Hills _ also were booked at the county jail and then turned over to state juvenile authorities.
Tierney urged anyone with information about Addison to call the sheriff's tip line at 1-888-ANY-TIPS (269-8477) or to call 911.
