A recently released convicted felon accused of three carjackings in the metro area over the weekend had an ankle monitor, which helped put him at locations of the crimes.

This according to the probable cause affidavit obtained by 9Wants To Know.

Tremaine Speer, 32, had his first court appearance at the Arapahoe County Courthouse Thursday morning. He’s facing several charges, including aggravated robbery, possession of a weapon by previous offender and aggravated motor vehicle theft.

At the time of Speer’s first alleged carjacking in Littleton Saturday, he’d been out of prison for 31 days.

According to court documents obtained by 9Wants To Know, on July 30 around noon, Speer carcjacked a woman in Littleton, telling her, “Get the **** out of the car,” while he held a black handgun to the left side of her face.

The document states Speer “forced her out of her car by grabbing her left arm and pulling her out of the vehicle.”

When Speer drove away in the stolen car, he was followed by a woman driving the car he’d arrived in.

According to the probable cause affidavit, the second carjacking happened Sunday July 31 just after 2 p.m. This one happened in the parking lot of the Littleton Museum. The man told the victim “get the ** out of the car.” The victim pulled the keys out of ignition and the man hit her on the forehead three times with the barrel of a gun. The attacker, believed to be Speer, also slapped her with his hand.

Sunday night, Aurora police responded to an armed carjacking, where a woman’s car was taken in her driveway with all her belongings inside. Speer is a suspect in that incident as well.

Court documents say the Colorado Department of Corrections tracked Speer’s ankle monitor data to all three carjacking locations.

Two of the three victims identified Speer as their assailant.

Aurora Police have asked 9NEWS not to show Speer’s photo as it would interfere with their investigation. A spokesperson told 9NEWS APD is looking at Speer as a suspect in other crimes.
