DENVER (CBS4) – A carjacking suspect has been arrested after investigators believe he could be linked to three crimes in two different cities.

In Littleton, police investigated two carjacking cases that occurred last weekend and determined they may have been related.

“I thought someone was joking with me. I thought it was somebody I know. I went to say something back to him and that’s when he put the gun to my head,” said the victim in the first carjacking who asked not to be identified. “My life is way more important than my vehicle.”

The second carjacking happened about 2:30 p.m. Sunday in the parking lot of the Littleton Museum.

Police in Aurora investigated a carjacking that occurred on Sunday. Similarities in that case to the cases in Littleton led investigators to believe they were related.

“The descriptions of the suspect were very similar and methods similar,” said Littleton Police Cmdr. Trent Cooper.

Speer, 32, was located in the area of 30th and Fox Street in Denver and arrested about 11:20 p.m. on Tuesday.

Speer has a violent criminal history but was released from prison on parole in June.

“This is an excellent guy to have off the streets,” said Cooper.

Speer remains in custody on a parole violation charge pending the filing of charges related to the carjackings that may include assault, robbery and motor vehicle theft charges.
