SAN ANTONIO ā A 25-year-old man was arrested and charged with murder after San Antonio police said he shot an elementary school teacher outside of his Northwest Side apartment earlier this month.
Mathew Thomas Wiessing was taken into custody Thursday in connection with a fatal shooting that happened before 7 a.m. on March 10 at the Eckert Heights Apartments, in the 4800 block of Gus Eckert.
When officers arrived at the scene, they found the victim, Michael Echaniz, 23, in the parking lot and he had several gunshot wounds in his upper extremity.
Police said he lived alone at that apartment complex and was a teacher at Great Hearts Forest Heights. Authorities believe Echaniz was trying to get inside of his vehicle when he was gunned down.
He was pronounced dead by EMS and witnesses told officers they saw an individual in a black hoodie running from the scene.
As the investigation continued, SAPD received a tip from one of Wiessingās family members, sharing information on the murder and confirming that he was involved.
Police said they located Wiessing and conducted a traffic stop on March 10. He agreed to talk with officers but during the interview, he was evasive and didnāt answer many questions, SAPD said.
Wiessing was later released, as police said they didnāt have enough evidence in the case, nor probable cause.
Homicide investigators collected surveillance video, which showed Wiessing going to the crime scene and fleeing after the shooting occurred.
Further evidence was collected and SAPD was able to obtain an arrest warrant for Wiessing. On Thursday, he was taken into custody without incident for Echanizās murder.
Authorities believe Wiessingās motive stemmed from Echaniz dating his ex-girlfriend after their relationship ended several months ago.
One of Wiessingās relatives told police that he āhad been taking the breakup poorlyā and was leaving at odd hours of the day and night, according to an arrest warrant affidavit.
The relative also stated that on the day of the homicide, Wiessing returned home and washed a dark-colored hoodie, the affidavit states.
A 9mm handgun was believed to be used in the fatal shooting, though officials havenāt yet recovered the weapon.
