Butler police display stolen guns, crack and currency they recovered from two houses during warrant searches Monday. Six people were arrested.

An ongoing Butler police investigation into a series of home break-ins and stolen guns netted six arrests since Monday.

But investigators are still tirelessly and tediously working the case, said Deputy Chief David Adam.

“They're very busy,” Adam said of the department's detectives and officers.

More charges and additional arrests are expected.

Key evidence in the investigation came Monday when police raided two city homes — one on the 400 block of West Penn Street and the other on South Street.

In all, officers, aided by troopers, turned up four guns, at least three of which were stolen. They also seized more than 1½ ounces of crack cocaine and more than $3,700 in currency.

Police on Monday charged David E. Lamison, 53, and Justin D. Ratelle, 28, who live at the home on West Penn Street, with having two stolen guns that were taken in separate burglaries. Also charged Monday were Johnny T. McCray Jr., 29, Colleen L. Christie, 47, and William L. Gold, 49, who all live at the home on South Street, where police seized one stolen gun as well as the crack and currency.

Police on Tuesday charged David W. Eberhardt Jr., 26, who has no known address, with three burglaries in Butler.

All but Christie are in the Butler County Prison on $100,000 bail each. Christie is free on $25,000 unsecured bail.

Eberhardt is accused of break-ins at homes on the 600 block of North Chestnut Street, the 500 block of Federal Street and on Summit Street.

But Adam said Eberhardt is also a suspect in “several” other burglaries. He declined to elaborate.

He was taken into custody Monday at a vacant apartment on the 300 block of North Elm Street, where police found him while responding to a suspicious activity call.

He was caught, investigators said, with a cell phone taken from the house on Summit Street that was burglarized Saturday. A .40-caliber Glock pistol also was stolen.

Eberhardt during an interview at the station admitted that he and another man broke into that home and took a gun and a spare magazine, according to the police search warrant application for the West Penn Street house.

He acknowledged, police said, exchanging that gun for $70 worth of crack.Officers served the search warrant at 8:15 a.m. They found Lamison and Ratelle at the home.Also discovered was a 9 mm Taurus pistol that police believe was taken in the break-in at the North Chestnut Street home and a .380-caliber Ruger stolen in a burglary Saturday at a home on Orchard Avenue.A third gun seized at the West Penn Street house, a .22-caliber revolver, could not be traced because its serial number had been altered.At an interview at the Butler police station, investigators questioned Lamison about the recent string of burglaries in the city.He said that he “often buys items from individuals and knows that some of them may be stolen,” according to court documents.He also admitted, police said, that a man he knew as “David” had recently given his roommate two firearms that he described as being a Ruger and a .22-caliber handgun.Investigators said they asked Lamison specifically about the Glock pistol taken from the house on Summit Street. He recounted that “David” brought it to his home on Saturday.Lamison said that he and Ratelle later took the gun to a home on the city's south side where they swapped it with a man named “Mitch” for crack, documents said.Using an Internet map, he was able to identify for police where he and Ratelle took the gun — the home shared by McCray, Christie and Gold.The information helped police secure a second search warrant Monday, this one for the trio's residence on South Street.Police said they found all three defendants home when they served the warrant about 2 p.m. They also subsequently found the Glock stolen in the burglary at the Summit Street home.But that's not all officers turned up. They found three plastic bags containing a combined 45 grams of crack and $3,729 in currency.Eberhardt is charged with three counts each of burglary and trespass, all felonies.Lamison and Ratelle are both charged with two counts each of receiving stolen property and conspiracy, all felonies.McCray, Christie and Gold are all charged with receiving stolen property, possession with intent to deliver a controlled substance and conspiracy, all felonies. They also are all charged with misdemeanor drug possession.Additionally, McCray is charged with another felony — felons not to possess firearms. Police in charging documents noted that he has a 2011 conviction for burglary.
