A ninth arrest has been made in the deaths of Colorado Springs teens Derek Greer and Natalie Partida, according to the El Paso County Sheriff's Office.

Following an hours-long search Friday evening authorities arrested Carlos “Tink” Meza near Dorchester Park in Colorado Springs. Earlier in the week the sheriff’s office asked for help in locating Meza and Endo Velarde. Velarde remains wanted by authorities. Meza was wanted on suspicion of possession of a weapon by a previous offender, a felony, court records show.

Earlier on Friday 20-year-old Breeana Eloise Dahlberg was taken into custody on charges of 2nd-degree kidnapping and marked the eighth arrest in the case. Dahlberg and Meza’s arrests come two days after Angelita Prado, 22, was taken into custody on kidnapping charges related to the double homicide.

Velarde, also known as Sleepy, is a Hispanic male, stands at 5'8", weighs about 135 pounds, has black hair and brown eyes.

Alander Jordon Wilson marked the sixth arrest and was taken into custody on suspicion of attempting to influence a public servant, according to the Sheriff's Office. Just hours before announcing Wilson's arrest, the Sheriff's Office asked for the public's help finding another man wanted in the double homicide investigation.

Derek, 15, and Natalie, 16, were found dead March 12, their bodies left lying on the shoulder of Old Pueblo Road in rural El Paso County near the Pikes Peak International Raceway.

Their deaths have been ruled homicides, but authorities have withheld the cause pending completion of toxicology tests.

Five other people have been arrested in the ongoing investigation.

Four were arrested on suspicion of two counts each of first-degree murder: Gustavo Marquez, 19, Diego Chacon and Joseph Arthur Rodriquez, both 18, and Marco Antonio Garcia-Bravo, 20.

Marquez was also arrested on two counts of second-degree kidnapping and two counts of aggravated robbery, plus one count of child abuse resulting in death. Chacon, Rodriquez and Garcia-Bravo were also arrested on two counts each of second-degree kidnapping.

Alexandra Marie Romero, 20, was arrested on suspicion of second-degree kidnapping and accessory.
