Person of interest arrested in serial rape case - Dallas News |

Dallas PD: "This is an active and open investigation"

Posted: Updated:

Dallas police said the investigation into nine sexual assaults in Fair Park remains "active and open" despite the arrest of a person of interest early Friday morning.

Alan Mason, 29, was taken into custody for outstanding warrants. Dallas police said there are no charges pending against him other than for a probation violation.

Investigators found his silver Honda outside a Mesquite residence. A relative inside told police they could find him at an apartment in the 2500 block of Summer Tree Circle in Arlington.

Police began searching for Mason on Thursday after they received a tip from someone who told them Mason said he, "needed to get out of town because he had done something wrong."

Mason's profile and vehicle potentially link him to the crimes, police said. He is about the same size as the suspect and wears the same type of glasses described by some of the victims. He also drives a silver Honda, which is in line with reports that the attacker drives either a gray Honda Civic or an older model gray Volvo sedan.

However, Mason's grandmother said she believes police have the wrong man. She told FOX 4 he is a college-educated man with a good job and no reason to rob or rape anyone. She also said she's been driving his silver Honda for the past year and that he doesn't wear glasses.

A ninth victim in the serial rape investigation came forward on Thursday. Dallas police said she was attacked at some point in late July in the 2700 block of Morning Avenue. All of the attacks happened between June 22 and Sept. 1, all in the early hours of the morning.

A sister of one of the victims said she was attacked at 4 a.m. while walking home from a fast food restaurant. She is upset that it's taken so long to get DNA results from a rape test following the June attack.

Police said DNA testing is being expedited, something Mason's grandmother hopes for as well. She believes the results will prove her grandson's innocence.

"Let's stay measured on the apprehension of the person of interest. He is not charged. This may take numerous twists and turns," Dallas Police Chief David Brown said on Twitter Friday morning.

Police said Mason cooperated fully with investigators after his arrest. He is considered a person of interest, but police said the suspect could still be out on the streets. DPD will continue to leave its resources in the area where the rapes occurred and tips from the public are still welcome.

Concerned residents asked questions about the investigation at a community meeting Thursday night at the True Lee Missionary Baptist Church. Many angry South Dallas residents also pointed fingers at police for not doing enough. Others urged their neighbors to do more, by keeping watch and reporting anything suspicious.

The reward for information leading to an arrest in the case now stands at $15,000.
