UPDATE FEB 22: A federal criminal complaint into the man accused of shooting four people within a week gives more details into the crimes.
There are more details about the first shooting in Logandale on Jan. 29 around 12:30 a.m. A man was working at Green Valley Grocery, cleaning out the car wash when the suspect vehicle arrived. The man asked when the nearest Smith's was and the worker responded while turning his back. While his back was turned, he heard two gunshots. The worker ran into the store when he realized he had been struck in the upper arm.
Another shooting was reported near Rancho Drive and Washington Avenue around 3 a.m. and another man was shot around 3:45 a.m. near Veterans Memorial Drive and Washington Avenue. The first man died while the other survived. The second man thought he had an abscessed tooth before finding out he had been shot in the head.
The fourth shooting, also fatal, was reported on Feb. 2 near 14th Street and the U.S. 95 overpass.
An analysis of the bullets from all four shootings found the same gun fired all of them and the bullets could be fired from the gun that Castellon had purchased.
On Feb. 8, Joshua Castello was contacted by Las Vegas police on Washington Avenue after he was discovered sleeping in a Hyundai Tucson -- the suspect vehicle. The clothes he was wearing also matched the description of the shooter.
He told police that he was too tired to leave the SUV to go into his sister's apartment. A small bullet hole was found in the vehicle, which Castellon told police was from a friend firing a shotgun round. The federal complaint said the hole was inconsistent with a shotgun.
On Feb. 15, police contacted Castellon's estranged wife, who told them that her husband had bought a credit card on Jan. 20 and then bought a Taurus .357 caliber revolver from SportsmansOutdoorSuperstore.com that was shipped to Northwest Arms -- a federal firearms licensee -- on Jan. 26. Castellon received the gun on Jan. 26, just days before the shootings began.
Castellon's wife told police that she asked him if he was the man in the surveillance video but he denied it.
Castellon is being federally investigated for falsifying a written statement, possibly to deceive a federal firearms licensee. In order to buy the firearm, Castellon stated he was the intended buyer/transferee, according to the complaint. He said he intended to resell the gun to a friend of a friend, which meant he obtained the firearm on behalf of another person. Castellon was not the buyer/transferee as first stated.
UPDATE FEB. 20: Las Vegas police gave an update Tuesday in regards to a serial shooter case.
Police announced that a man has been taken into custody in this case. He has been identified him as 26-year-old Joshua Castellon.
Las Vegas Metropolitan Police Department Lt. Dan McGrath said the man is a local. He was arrested on Feb. 16 by a special agent with the Federal Bureau of Alcohol, Tobacco and Firearms on a federal weapons charge related to LVMPD's case.
On Feb. 20, an arrest warrant was issued for Castellon on two counts of murder and two counts of attempted murder.
Castellon will be booked into the Clark County Detention Center after the resolution of the federal case.

LAS VEGAS (KTNV) -- Las Vegas police are looking for a man wanted in four separate shootings in Clark County within a week.
Capt. Robert Plummer said police discovered a shooting in Logandale on Jan. 29. The same day, a homeless man was shot and killed at Rancho Discount Mall near Charleston Boulevard and Rancho Drive, and another homeless man was shot in the face near Las Vegas Boulevard and Washington Avenue.
Homicide detectives determined all three of these shootings were done using the same gun by the same man, who police said also shot and killed a homeless man under the U.S. 95 bridge at 14th Street on Feb. 2.
UPDATE on three recent homeless killings: @LVMPD says there was a fourth shooting. All 4 shootings are related. Last 9 days - 4 people were shot by the same suspect. 2 died, 2 injured. pic.twitter.com/9Of6CKU4it
All three of the homeless victims were sleeping when they were shot, Plummer said.
Plummer said the man wanted in the shooting doesn't match the FBI's definition of a serial killer, which means 3 people killed in a short period of time. Two people died while two were injured. Plummer did say this man was on his way to becoming a serial killer and called him a serial shooter.
"We must stop this man before he shoots and kills someone else," Plummer said.
Police said the shooter is a man about 6 feet tall, driving a 2016-2018 Hyundai Tucson sport limited SUV with the color being either silver, gray or a lighter blue.
Plummer asked the public to share any surveillance from the area of the shootings in Las Vegas, including Charleston Boulevard to Washington Avenue, Rancho Drive to Valley View Boulevard, Stewart Avenue to Bonanza Road and Maryland Parkway to Eastern Avenue.
